About SRG GROUP LIMITED
Founded on the principles of precision and durability, SRG GROUP LIMITED has grown into a premier manufacturing exporter dedicated exclusively to bearing accessories. We specialize in producing heavy-duty adapter sleeves, withdrawal sleeves, and lock nuts that withstand the most demanding industrial environments. Over the past 15 years, our engineering team has continuously refined our heat treatment and surface grinding processes, ensuring every sleeve delivers maximum clamping force and flawless concentricity for your machinery.
Zero-Defect Quality Control Standard
Quality at SRG GROUP is measured in micrometers. Operating under a strict ISO 9001 quality management framework, our internal standards match and exceed global expectations. We utilize specialized thread gauges, Rockwell hardness testers, and precision magnetic particle testing to ensure zero micro-cracks and flawless thread accuracy on every single sleeve. Our structural tolerance control is strictly limited within standard international boundaries, ensuring that our products serve as perfect, high-performance replacements for premium brands like SKF and FAG without requiring any machine re-calibration.

Quality craftsmanship
Production line
High-Capacity Automated Machining
Our workshop is equipped with over 20+ advanced CNC lathes and 3 fully automated, continuous production lines. With a stable monthly capacity exceeding 200,000 pieces, we efficiently handle both high-volume standardized orders and flexible small-batch custom production with consistent precision.
Advanced Technology
Premium Material & Heat Treatment
We source certified carbon steel and implement specialized heat treatment processes aligned with German and Japanese industrial standards. This ensures our sleeves possess optimum tensile strength and wear resistance, perfectly matching the requirements of heavy machinery, mining, and agriculture.
Quality Control System
Multi-Stage Precision Inspection
Our quality assurance involves a 5-step process: incoming material analysis, in-process dimension checks, surface roughness testing, thread fit verification, and a 100% pre-shipment inspection. We guarantee that no sub-standard product ever leaves our facility.
