What is R4 bearing?

What is R4 bearing?

The R4 Deep Groove Ball Bearings is an open style bearing. The R4 0.25 mm Ball Bearing Inner Dimension 0.25mm X Outer Dimension 0.625mm X Width 0.196mm is an open style ball bearing designed for high rotational speeds and high dynamic loads.

What is the difference between 2RS and ZZ bearings?

Type 2 RS is a sealing type with a moulded rubber seal on both sides. Type 2 Z or ZZ is a non-removable, non-contact bearing closure with a metal seal on both sides. This type of seal doesn’t make contact with the inner ring therefore, there would be no impact on the operational speed.

What kind of ball bearing does a r4-2rs have?

The R4-2RS and R4-ZZ is a 1/4 ball bearing that is found in many applications. The R4-2RS ball bearing has two contact rubber seals one on each side of the ball bearing. The R4-ZZ ball bearing has two non-contact metal shields one on each side of the ball bearing.

What are the different types of rolling bearings?

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed.

What kind of steel is a ball bearing made of?

The bearing is made of chrome steel for durability and resistance to deformity under heavy loads, and it has rubber seals on both sides of the bearing to keep lubricant in and contaminants out. This deep-groove sealed ball bearing is suitable for use in electric motor applications.

What kind of ball bearing does PGN use?

PGN’s R4rs (1/4″x5/8″x0.196″) is a single-row bearing that supports radial loads, made with Chromium Steel providing superior quality and durability. It comes pre-lubricated and shielded to keep the lubricant in and contaminants, dirt and debris out.
