HZK Deep Groove Ball Bearings are primarily designed to withstand radial loads. When operating solely under radial load, the contact angle is zero. Increasing the radial clearance allows them to achieve angular contact bearing performance, thus supporting combined radial and axial loads. The axial load limit is generally 0.25-0.5 times the rated static load. They are capable of self-aligning within a range of 2'-10', but require high concentricity in the mounting seat, and tilting may affect service life. The standard series includes single-row and double-row, stainless steel, and ceramic types. Suffixes such as M (brass cage) and 2RS (double-sided seal) are used to distinguish these characteristics.
Deep groove ball bearings have a particularly wide range of applications. Consequently, they are available in a wide variety of types and sizes. The HZK standard series includes the following types: ,Single-row deep groove ball bearings , Single-row deep groove ball bearings with filler grooves , Stainless steel deep groove ball bearings ,Double-row deep groove ball bearings – Ceramic deep groove ball bearings , Deep groove ball bearings for high-temperature applications.
HZK deep groove ball bearing suffixes:
M: Machined brass cage, steel ball guide
2RS/2RSR: Double-sided seals
W203B: Stainless steel bearings
2Z/2ZR: Double-sided anti-layer caps
