IKO (Nippon Thompson) linear guides, needle roller bearings and tables

IKO linear guides, needle and crossed roller bearings, spherical bushings and mechatronic tables made by Nippon Thompson. Selection by series and a quotation for your project.

Linear Way profile rail guides

Ball-type Linear Way guides of the LWE, LWH, ME and MH series use four-point contact. Roller-type LRX and MX guides carry roughly twice the dynamic load. IKO linear bearings for machine tools range from 8 to 85 mm, and ME, MH and MX come with C-Lube lubrication.

Miniature Linear Way and ball splines

Miniature LWL, LWLF, ML and MLF guides start from a 1 mm rail width and serve semiconductor, medical and laboratory equipment. LSAG and MAG linear ball splines transmit torque during axial travel. Spline shaft diameters run from 2 to 27.2 mm.

Crossed roller ways and crossed roller bearings

CRW crossed roller ways come in rail widths from 8.5 to 110 mm. CRB crossed roller bearings take radial, axial and moment loads at the same time. Bearing section heights run from 5 mm on slim series to 150 mm.

Needle roller bearings and cam followers

NA49, RNA49 and TAF needle roller bearings come in bores from 5 to 490 mm with dynamic load ratings up to 1,910 kN. AZK and NTB thrust bearings pair with WS and GS rings. CF...B, CFKR and NUCF cam followers with thick outer rings absorb impact.

Spherical bushings and rod ends

Steel-on-steel GE…ES spherical bushings come in bores from 4 to 300 mm, with static ratings up to 26,500 kN on the largest sizes. Series with a PTFE liner run without relubrication. PHS and POS rod ends come with M3 to M30 threads.

Linear motor tables and ball screw tables

Linear motor tables give strokes from 8 to 2,760 mm, speeds up to 3,000 mm/s and 0.1 to 0.5 µm repeatability. Ten ball screw table series cover strokes up to 1,400 mm. Each module ships as a tuned, tested system of guide, drive, frame and feedback.

How to choose an IKO component

Selection starts with the type of motion.

For straight travel IKO makes Linear Way guides, miniature guides, CRW crossed roller ways and linear ball splines; for rotation, needle roller, thrust and crossed roller bearings and cam followers; for swivel and misalignment, spherical bushings and rod ends; for complete axes, linear motor tables and ball screw tables.

Next come load and its direction, required rigidity, accuracy grade, preload and environment: C-Lube versions suit clean rooms and places without lubrication access, and stainless steel suits corrosive conditions.

The manufacturer

IKO is the brand of the Japanese company Nippon Thompson Co., Ltd., founded in 1950. In 1959 it became the first maker of needle roller bearings in Japan, and in 1978 it introduced its first Linear Way guide.

Products are made at nine plants in Japan, and regional R&D centers operate in Santa Fe Springs, Düsseldorf and Shanghai.
