Jiachen / Jiachen Precision — Precision Roller Cam Bearings for Machine Tools

Global supply of precision roller cam followers and bearings by Jiachen (Taiwan / Jiachen Precision Co., Ltd.). Standard, hollow, side-mount, rear-pull, heavy-duty, and full-needle bearings for CNC 4th/5th-axis rotary tables and automatic tool changers from SpareX.

Jiachen Standard Type Precision Roller Cam Bearings

Standard roller cam bearings by Jiachen span outer diameters from 5.4 mm up to 110 mm. Precision cylindrical grinding delivers inner bore cylindricity below 1 µm and concentricity within 2 µm. Assemblies serve as primary rolling followers in high-rigidity CNC machining centers and index drives.

Jiachen Precision Roller Cam Bearings and Machine Tool Motion Components

Taiwanese manufacturer Jiachen Precision Co., Ltd. has dedicated over two decades to developing specialized roller cam followers, cam bearings, and precision motion assemblies for machine tools.

The comprehensive production line comprises Standard Type bearings, Side Type mountings, Rear Type draw-in configurations, lightweight Hollow Type variants, Enhanced heavy-duty series, and Full Needle Groove assemblies covering outer diameters from 5.4 mm up to 110 mm.

Manufacturing facilities feature Japanese MIYANO CNC lathes and precision cylindrical grinding centers capable of achieving inner diameter cylindricity below 1 µm and concentricity within 2 µm.

For high-speed rotary tables (4th and 5th axes) and Automatic Tool Changers (ATC), Jiachen applies Diamond-Like Carbon (DLC) surface coatings that eliminate backlash and withstand demanding continuous machining cycles.

Engineering Selection Guidelines, Alignment Standards, and Maintenance

Selecting optimal Jiachen cam followers requires matching mechanical indexing architecture, outer roller diameter, and dynamic radial load ratings.

SpareX engineering teams assist equipment manufacturers and retrofitters with dimension verification, tolerance validation, and preload adjustments to achieve absolute zero backlash in globoidal and barrel cam indexers.

Preventive maintenance includes periodic journal inspection, dial indicator runout checks down to 0.001 mm, rolling element wear evaluation, and lubrication line verification.

SpareX coordinates global supply chains to deliver inspected Jiachen Precision motion components backed by factory quality documentation.
