BW-Fixatoren precision leveling wedges and machine mounts
BW-Fixatoren precision leveling wedges: Series RK, LK, S, ME, LS, SW, EK, anchor bolts, and sealing covers. Technical selection based on machine loads.
Series RK precision leveling wedges for rigid machine tool anchoring
BW-Fixatoren Series RK precision leveling wedges deliver dependable alignment for heavy machine tools, milling centers, and presses. Manufactured from high-grade grey iron treated with molybdenum disulfide, these elements maintain fine adjustment accuracy under loads reaching 1,200 kN.
- Six standardized frame sizes from RK I to RK VI handling static loads up to 1,200 kN
- Fine height adjustment pitch ranging from 0.25 to 0.50 mm per single screw revolution
- Direct anchor bolt connection through equipment feet utilizing elastic Wellenstein bolts
- Three integrated leveling screws included for initial elevation setup prior to grouting
Series LK adjustable leveling mounts for vibration-damped equipment setup
BW-Fixatoren Series LK leveling elements are engineered for freestanding and vibration-isolated installation of production machinery. The wedge mechanism is mechanically locked against vibration-induced drift, allowing rapid realignment without mandatory floor anchoring.
- Efficient damping of structural vibrations, mechanical shocks, and acoustic resonance
- Smooth wedge traversal equipped with positive retention against dynamic vibrations
- Flexible deployment options supporting loose floor placement or stud anchor mounting
- Swift compensation for foundation settlement, floor contraction, and thermal shifts
Series S top-adjusted leveling wedges for large clamping plates and beds
BW-Fixatoren Series S leveling units are tailored for heavy floor plates, clamping beds, and sprawling machine structures where lateral side access is obstructed. Height adjustment is operated from above through vertical access ports using standard socket tooling.
- Convenient top-side elevation adjustment through machine plate apertures without side reach
- Six standard sizes from S I to S VI offering micrometer positioning for heavy table slabs
- Full compatibility with Series D sealing covers to protect vertical adjustment shafts
- Uniform load sharing across extended machine foundation rails and testing surfaces
Series ME alignment elements for electric motors, pumps, and compressors
BW-Fixatoren Series ME positioning assemblies deliver precise dual-axis alignment for motor drives, high-pressure pumps, and industrial compressors. The mechanism provides independent vertical and horizontal screw adjustments to achieve precise shaft alignment.
- Independent micrometer adjustment along vertical elevation and horizontal planes
- Elimination of angular and parallel shaft misalignment on motor-gearbox drive trains
- Mitigation of flexible coupling fatigue and prevention of premature bearing wear
- High modular adaptability fitting tailored motor foot dimensions and bed configurations
Series LS extended-stroke wedges and Series SW lateral alignment stops
Series LS and SW expand the BW-Fixatoren precision mounting portfolio. LS models featuring extended adjustment travel serve auxiliary equipment such as pallet shifters and tool magazines, while SW lateral stops absorb heavy horizontal cutting reactions from machine tools.
- Extended vertical adjustment travel in Series LS tailored for auxiliary machinery units
- Integrated spherical washer in LS units compensating for non-parallel mounting surfaces
- Heavy-duty Series SW lateral wedge stops absorbing substantial horizontal dynamic thrust
- Secure retention of machine beds under high-speed milling and reversing inertia forces
Series EK compact leveling wedges and Series D Abschlussdeckel sealing covers
BW-Fixatoren Series EK compact leveling elements deliver a cost-effective alignment solution for secondary machinery without compromising precision. Heavy-duty Series D sealing covers and oil tray systems shield adjustment wells from coolant fluid, lubricating oil, and metal swarf.
- Cost-efficient single-wedge Series EK architecture suited for standard installation duties
- High static load resilience housed within compact, space-saving grey iron geometry
- Series D closure covers with single-screw fastening for rapid dust and fluid sealing
- Complete isolation of bed internal adjustment ports against synthetic cutting emulsions
German machine tool engineering traditions and BW-Fixatoren heritage
Fixatorenbau Bertuch & Co. GmbH located in Leverkusen has developed and manufactured precision leveling elements for the global machine tool industry for more than six decades.
The BW-Fixatoren brand stands as an international benchmark for rigid foundation anchoring and high-accuracy equipment leveling.
The manufacturing scope includes leveling wedge series RK, LK, S, ME, LS, SW, and EK alongside sealing covers and foundation anchors. High-density grey iron components treated with anti-friction molybdenum disulfide ensure smooth wedge movement under static loads exceeding hundreds of tons.
Leveling wedge mechanics and micrometer bed positioning accuracy
At the heart of every BW-Fixatoren leveling element lies a precision low-angle wedge mechanism converting screw torque into controlled vertical travel.
An elevation adjustment range of 0.25 to 0.50 mm per single screw revolution enables alignment of heavy milling machines to hundredths of a millimeter.
The integration of spherical seating washers prevents point edge loading and bending stresses on anchor studs when mounting on uneven foundation surfaces. Once aligned, the internal wedge mechanism remains securely locked against dynamic shocks and machining vibration.
Foundation anchoring technology utilizing elastic Wellenstein bolts
To achieve rigid backlash-free connection between machine feet and foundation concrete, specialized Wellenstein elastic anchor bolts are deployed. Operating through the center passage of Series RK wedges, these high-tensile bolts absorb heavy dynamic stresses and alternating machine reactions.
This configuration prevents fastener fatigue failure under dynamic tilting moments typical of gantry mills and horizontal boring machines. Support for split anchor bolts and chemical adhesive capsules streamlines machine installation during shop floor reconstruction.
Top-side adjustment architecture of Series S for large floor plates
Mounting extensive surface plates, modular clamping tables, and long multi-section machine beds frequently restricts lateral access to perimeter adjustment screws. For such installations, BW-Fixatoren developed Series S wedges whose adjustment screw is accessed vertically through the table plate.
Technicians perform precision alignment from above using standard socket tools without removing fixtured tooling. Following alignment, vertical inspection wells are sealed with Series D closure covers, preventing ingress of cutting swarf and liquid emulsions.
Dual-axis shaft alignment mechanics engineered in Series ME assemblies
Precise collinear alignment between drive motors, centrifugal pumps, compressors, and gearboxes is essential to prevent premature bearing and coupling degradation. BW-Fixatoren Series ME positioning elements deliver independent micrometer adjustment across vertical elevation and horizontal planes.
Decoupled coordinate positioning eliminates parallel and angular shaft runout in a single maintenance cycle without deformable shims. The modular structure accommodates varied drive foot patterns and foundation rails, sustaining precise alignment under heavy rotational torque.
Bed cavity isolation utilizing Series D Abschlussdeckel sealing covers
Penetration of synthetic cooling fluids, lubricating oils, and abrasive metal swarf into leveling cavities risks thread seizure and anchor corrosion. Series D Abschlussdeckel sealing covers are engineered to provide complete isolation of foundation pockets and machined bed apertures.
The expanding central bolt mechanism forces an oil-resistant elastomer seal against cavity walls without requiring internal threading. Paired with dedicated oil tray systems, these covers protect foundation concrete from aggressive machining fluids, extending production lifespan.
