Technical Specifications
Engineering data to help buyers prepare model, suffix, clearance, cage, bore, dimension, and document details before RFQ review.
Technical Routes for RFQ Preparation
Use this hub to prepare details before asking TFL Bearing to review availability, production, replacement, or document options. Dedicated technical pages should focus on practical RFQ tables as they are produced.
Clearance
C2, CN, C3, C4, C5, and application-specific clearance review
Suffixes
Cage, lubrication, bore, clearance, and design suffix preparation
Cage Types
CA, CC, MB, MA, and brass cage review for RFQ preparation
Tapered Bore
K, K30, shaft, and sleeve requirement preparation
Adapter & Withdrawal Sleeves
Sleeve and accessory details for tapered bore RFQs
HS Code
Export classification and customs document preparation can be reviewed with RFQ details

- • ABEC-1 through ABEC-5 equivalent
Internal Clearance
- • C2 — less than normal
- • CN — normal (standard)
- • C3 — greater than normal
- • C4, C5 — for high temperature / interference fits
Cage Types
- • CA — machined brass, prong-type
- • MB — machined brass, window-type
- • CC — stamped steel
- • MA — machined brass, outer ring centered
Material & Heat Treatment
- • GCr15 / 100Cr6 bearing steel
- • Through-hardened or case-hardened
- • Salt bath quenching process
- • 58–64 HRC raceway hardness
