Product Details
SKF-Grade Thrust Ball Bearings – High-Precision Axial Load Solutions
| Description | Key Selling Points |
|---|---|
| Models: 51104, 51204, 51304, 51105, 51205, 51305 | Wide range for scalable axial load needs (20–25 mm bore) |
| Dimensions: 20×35×10 mm (e.g., 51104) | Tight tolerances, ISO-standardized for drop-in SKF replacement |
| Precision Ratings: P0 to P2 | Ultra-precise P2/P4 options — ideal for high-speed machinery & CNC spindles |
| Lubrication: Grease or oil compatible | Pre-lubricated with premium lithium grease; extended service life |
| Vibration Class: Z1V1 to Z3V3 | Low-noise operation — critical for medical devices & precision instruments |
| Material: High-carbon bearing steel (GCr15 equivalent) | Heat-treated for hardness ≥60 HRC; fatigue resistance >1.2M cycles |
| Non-aligning, single-row, separated design | Easy installation & maintenance; perfect for rigid shaft support |
| Certified: ISO 9001:2008 | Full traceability & batch-tested quality control |
| OEM/ODM supported + China origin (HS Code 8482102000) | Cost-effective alternative to SKF without compromise on specs |
| In stock | Carton/pallet packaging | Same-day dispatch — no lead time delays |
Applications: Hydraulic pumps, automotive clutches, gearboxes, machine tool tables, and vertical motor thrust supports.
Why choose us over generic brands? Our bearings meet SKF dimensional & load specifications (dynamic Cr ≥ 12.7 kN for 51104), undergo 100% vibration & noise screening, and include material certs — not just packaging labels.
FAQ: Q: Are these direct SKF replacements? A: Yes — identical mounting dimensions and load ratings. Q: Can I get custom preload or special cages? A: Yes — OEM engineering support included. Q: Do you supply test reports? A: Absolutely — hardness, dimension, and vibration reports provided per batch.
