6903 2RSV MAX Bearing 17*30*7 mm 4Pcs Full Balls Bicycle Pivot Repair Parts 6903 2RS RSV Ball Bearings 6903-2RS 6903LLU

Product Overview

FUSHI 6903 2RSV MAX full ball bearings, sold in 4PCS per set, featuring standard precise dimensions of 17*30*7mm. Professionally customized forbicycle frame pivot, linkage and suspension moving parts, these high-precision deep groove ball bearings perfectly replace original worn, rusty, noisy and stuck pivot bearings. Adopting upgraded 2RSV enhanced sealing structure and full ball dense arrangement design, the bearings deliver higher load capacity, smoother rotation and stronger anti-fouling performance. Effectively solve problems such as frame pivot jitter, loose linkage, abnormal friction noise and unsmooth suspension compression/rebound, greatly improving bicycle riding stability and control accuracy.

Superior Product Features

1. Full Ball MAX Enhanced Load Structure
Different from traditional hollow semi-ball bearings, this 6903 2RSV MAX bearing adopts a full ball dense arrangement structure, which maximizes the number of steel balls inside the limited space. It effectively upgrades radial and axial bearing capacity, perfectly adapts to the high-frequency vibration and alternating load of bicycle frame pivots and linkage parts during off-road riding. It avoids bearing deformation, clamping stagnation and premature damage caused by long-term force, greatly extending the service life of pivot moving parts.

2. Upgraded 2RSV Reinforced Sealing System
Equipped with upgraded thickened high-elastic rubber sealing rings on both sides, compared with ordinary 2RS bearings, the 2RSV version has tighter fitting and stronger compression resistance. It can effectively block external mud, sand, rainwater, dust and sludge from invading the inside of the bearing, completely preventing internal steel balls and raceways from rusting, abrasion and oil drying. It maintains stable lubrication and flexible rotation for a long time, adapting to harsh riding environments such as mountain cross-country, muddy roads and daily rainy day riding.

3. High-Precision Wear-Resistant Bearing Steel
Made of high-quality GCr15 chrome bearing steel, with integral quenching and high-precision mirror polishing treatment on inner and outer raceways and steel balls. The bearing surface is smooth without burrs, with ultra-low rolling friction, no stagnation and no jitter during operation. It has excellent wear resistance and fatigue resistance, can withstand long-term high-frequency rotation and extrusion, and maintains consistent flexible rotation performance for a long time, reducing repeated maintenance troubles.

We provide a variety of pivots bearings, more information please contact us.

1. Why do the bearings I receive have shaking?

The clearance of the bearing is related to the play.
The default is the standard C0 clearance, which is usually 3-18um.
The corresponding principle is shown in the figure below.

If you don't need to shake, please choose C2 small clearance bearing,
If you have any questions, please contact us before purchasing.

2. What is the accuracy of ABEC-3?

ABEC is the American ANSI standard.
The corresponding German DIN standard and international ISO standard are as follows:
