🧩 Types of IKO Bearings
1. Needle Roller Bearings
Contain thin, long cylindrical rollers (needles).
Offer high radial load capacity in a compact design.
Common types:
Needle Roller Cage Assemblies
Drawn Cup Needle Roller Bearings
Machined Type Needle Roller Bearings
Thrust Needle Roller Bearings
2. Linear Motion Bearings / Guides
Enable precise straight-line motion.
Use recirculating ball or roller elements.
Types include:
Linear Way Series (LWL, LWU, etc.)
Linear Roller Way Super (SRG, etc.)
Precision Slide Units (ME, L, T types)
3. Cam Followers / Track Rollers
Used in automation, packaging, and conveyor systems.
Compact bearings with a stud and roller.
Types:
CF Series (Standard, Heavy-Duty)
NUCF (with thrust rings for better axial load support)
4. Crossed Roller Bearings
Handle radial, axial, and moment loads in a single unit.
Ideal for rotating tables, robotic joints, and medical devices.
Popular model: CRB / CRBC / CRBH series
