Oversized 932 Bearing Bronze Bars
- Yield Strength: 20,000 psi
- Hardness: Rockwell B35 (Soft)
- Temper: M07
- Heat Treatable: No
- Specifications Met: ASTM B505
The thickness and width are oversized to allow for finishing. Offering excellent antifriction qualities, 932 bronze also offers good strength and wear resistance. It's also known as SAE 660 and is often used for bearings, bushings, and thrust washers.

End Supports for Lead Screws and Ball Screws
A set of ball bearings reduces friction and secures the end of a ball or lead screw. Note: The end of your ball or lead screw must be machined before installing it into an end support.
For technical drawings and 3-D models, click on a part number.
End supports for combined radial and thrust loads handle radial loads (perpendicular to the lead screw) and thrust loads (parallel to the lead screw).
