36690/20 Double Row Spherical Roller Bearing 100x215x73mm Heavy Load Mining Crusher Bearing

1. Product Overview

36690/20 is double row heavy-duty spherical roller bearing, standard metric dimension 100mm inner bore × 215mm outer diameter × 73mm width.
Model Code Explanation:

- 36690/20: Standard heavy mining series spherical roller bearing, split code model commonly used in crushing and vibrating machinery
- Structure characteristic: Double row symmetric spherical rollers, spherical outer ring raceway, strong self-aligning performance, can bear huge combined radial load and bidirectional heavy axial load
Inner ring, outer ring and spherical rollers adopt high purity GCr15 bearing steel, after overall quenching and superfinishing treatment. Machined solid brass cage separates rollers evenly, avoids roller skew under severe vibration and impact load. Large roller contact area brings outstanding overload resistance and fatigue life. Open structure adapts circulating oil lubrication, suitable for continuous high-impact heavy-duty working conditions. Widely applied to stone crusher, vibrating screen, cement kiln supporting roller, mining conveyor roller, ball mill auxiliary shaft and all heavy vibration industrial equipment with shaft deflection.

2. Technical Specifications

Mounting dimension drawings, crusher assembly matching guides and heavy impact vibration durability test reports can be provided on customer request.

3. Core Advantages

• Spherical outer ring raceway + double row spherical roller design, excellent self-aligning ability, allows shaft deflection within ±2°, adapt to equipment foundation deformation and installation misalignment of vibrating screens and crushers.
• Double row large-size spherical rollers, ultra-large contact area, superior dynamic and static load capacity, stable operation under frequent heavy impact load of stone crushing production line.
• Integral machined brass cage, high strength and wear resistance, not easy to deform under long-term severe vibration, effectively eliminate roller skew and abnormal noise.
• High purity quenched GCr15 steel raw material, uniform metallographic structure, strong anti-fatigue and anti-spalling performance, greatly extend service life under cyclic impact load.
• Open through-type design without sealing barrier, circulating oil can fully circulate inside bearing, rapid heat dissipation to avoid high-temperature oil carbonization and bearing burning loss during continuous heavy-load operation.
• Unified interchangeable industry standard dimensions, fully compatible with global mainstream 36690/20 mining spherical roller bearings, direct replacement without modifying crusher housing and shaft structure.
• Multiple clearance options available: C3 general industrial clearance, C4 special enlarged clearance for vibrating screen, eliminate heat expansion jamming during long-time high temperature operation.
• Rich customizable options: Single/double lip contact seal upgrade, high temperature resistant bearing steel variant, OEM laser marking on outer ring, neutral export anti-rust carton packaging, extreme pressure heavy-duty grease pre-filling.
