Remark: 1. Basic rated load in the table is for reference only.
2. If the bearing adopts cylindrical outer pulley or spherical outer pulley, suffix R or X to bearing model.

Example:

Cylindrical outer pulley	Spherical outer pulley	Cylindrical outer pulley	Spherical outer pulley
CF5	CF5 R	KR13 X	KR13
CF10	CF10 R	KR22 X	KR22

3. If you need particular accessories, such as lubrication injection fitting, bolt or blanking adapter, give it clear in the order.
4. All the above curving rollers are hexagon type. If you need in-line type, give it clear particularly in the order.
5. All the above curving rollers are not eccentric. If you asks for eccentric type, like KRE 16 or CFE 16 BUU, give it clear particularly in the order.

The bolt of CYJ c. In order to avoid stress concentration, the exterior surface on the thick wall of roller is arc. The curving roller has many types, with double or single seal ring, or without seal ring. The roller with seal ring has large space for storing lubricant grease, so it can provide long-term lubrication and can prolong lubricating interval. The seal ring may be made from N220 or PTFE. Its running temperature is among -30°C- +100°C or -30°C - +180°C. Sealed curving roller can bear larger load but its rotate speed is very slow and it has to be lubricated usually.
