PRODUCT SPECIFICATIONS
The parameters below are confirmed against the application before a bearing is selected or ordered.
Bore, outside diameter and width establish the mounting envelope, while tolerance and precision class set the running accuracy the application requires.
Bearing steel grade and heat treatment influence hardness, dimensional stability and service life under load. Requirements are confirmed with the manufacturing partner.
Clearance group and precision class must suit the fits, the temperature difference in operation and the accuracy the equipment requires.
Seal or shield arrangement and lubricant selection follow the speed, temperature and contamination conditions at the bearing position.
Cage material and design affect speed capability, load distribution and guidance. Designation suffixes identify the arrangement supplied.
MANUFACTURING & QUALITY
HCT coordinates the technical and quality requirements of a project with selected manufacturing partners. Production processes are carried out by the manufacturing partner confirmed for the project.
Turning, heat treatment, grinding, superfinishing, assembly and final inspection are coordinated with specialised production partners according to product family, material and quantity.
Acceptance criteria, inspection scope and reporting are agreed before production. Manufacturing partners carry out the agreed production checks; third-party inspection can be arranged when specified.
INDUSTRIAL APPLICATIONS
Bearing type, arrangement and specification follow the duty of the equipment and the operating conditions at each position.
