DC motor deep groove balll bearings 1640

Product Description

Descriptions of dc motor ball bearing 1640

Deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread. The raceway grooves on both the inner and outer rings have circular arcs of slightly larger radius than that of the balls. In addition to radial loads, axial loads can be imposed in either direction. Because of their low torque, they are highly suitable for applications where high speeds and low power loss are required.

In addition to open type bearings, these bearings often have steel shields or rubber seals installed

on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common.

This bearing coms in both a sealed and a shielded version. Please select between the two below. Select 2RS for a sealed bearing or ZZ for a shielded bearing.

This bearing can be found with the following part numbers on it:
1640-2RS, 1640 2RS, 1640 RS, 1640RS, 1640-ZZ, 1640 ZZ, 1640ZZ, 1640 Z

The 1640-2RS and 1640-ZZ is a 7/8 ball bearing that is found in many applications. The 1640-2RS ball bearing has two contact rubber seals one on each side of the ball bearing. The 1640-ZZ ball bearing has two non-contact metal shields one on each side of the ball bearing. If your application requires a 1640 ball bearing with only one seal or shield you can get this ball bearing and take one of the shields or seals off. This 7/8 inch ball bearing is high quality and can take electric motor demands if needed.
