Part Number
Configured Part Number is shown.
Product Overview
1. Special Support Units for C7 to C10 rolled screw ball without pre-pressure.2. This product connects the support side (no motor connected) of the ball screw.
3. The product of Support Units is composed of bearing holders, bearings, and buckles.
| Item | MISUMI Standard Product | Economy Series |
| Bearing Used | Angular Bearings (1 set) | Radial Bearings (1 set) |
| Center Height Tolerance | -0.03 to 0 | ±0.03 |
| Applicable Ball Screw | All | Dedicated for Rolled Ball Screw |
While they are capable of handling axial load with preload applied,
we recommend use for low-speed and low-load applications upon confirmation of the allowable load.
Because the center height tolerance is also mitigated, in combination with a precision ball screw,
the precision ball screw specs may not be met.
(See the bottom of the standard tables for a table of combinations with rolled ball screws)

Frequently asked question (FAQ)
- Question: What does "applicable shaft diameter of oil seal" mean?
- Answer: The support unit purchased from MISUMI already includes the collar. The collar and the oil seal in the support have been matched, and it can be ignored as long as it is matched with MISUMI ball screw on sale according to the "Ball Screw Applicability Table". However, if it is matched with the ball screw purchased from other companies, please select the type according to shape and size of the shaft end of the screw.
- Question: What should I do if the accessories in the support unit are lost or damaged?
- Answer: All kinds of accessories can be sold separately, please select according to the MISUMI catalog
- Question: Square type support units are divided into standard type and narrow pitch type, what is the difference?
- Answer: In the case of limited pitch space, please use the narrow pitch type, but be sure to choose according to the shaft end size of the ball screw. For example: please use standard type (C-TEK) support unit for C-TBSE type ball screw and narrow pitch type (C-TBK) for C-TBSB type ball screw.
