1. Miniature deep groove ball bearing
Deep Groove ball bearings are the most common bearings and are used to reduce friction between rotating and fixed parts.
A deep groove ball bearing consists of an inner ring, outer ring, balls, a cage which has the task to keep a certain distance between the balls and possibly seals or covers.
Features:
Rings – Rings are typically made from corrosion-resistant, martensitic steel alloys.
Cages – Stainless steel ribbon cages are used as standard. For special applications, special plastic materials can be used.
Seals – HQW deep groove bearings are available in both sealed and open configurations.
Balls – Balls are usually made from stainless steel (X65Cr13). However ceramic balls (silicon nitride) are available for demanding applications.
Lubricants – Around 300 different types of grease and oils are available depending on application requirements.
2. Miniature angular contact ball bearings
Single row angular contact ball bearings support thrust loads in one direction and are often used in machine tool spindles. At very high speeds, these bearings can simultaneously absorb high radial forces and single direction axial forces.
Features:
Materials – Corrosion-resistant steel alloys are typically used for the rings and ceramic (silicon nitride) balls can be incorporated for high speed or demanding applications.
Seals – Sealed configurations are available for protection against contamination or where lifetime lubrication is a requirement.
Contact Angle – Angular contact ball bearings from HQW are available with different contact angles.
Preload – Bearings can be preloaded in back to back (DB), face to face (DF) or in a tandem (DT) arrangement depending on the application requirements. Universal bearings which can be paired in any arrangement are also available.
Tolerances – Miniature bearings from HQW can meet ABEC9 (ISO P2) standards where required
