SL045020PP2NR Double Row Full Complement Cylindrical Roller Bearing 100x150x67mm Sealed Locating Bearing

SL045020PP2NR double row full complement locating bearing, interchangeable with NNF5020ADA-2LSV, dimension 100×150×67mm.

Code Definition

• SL045020: Medium heavy full complement roller base model
• PP: Double-sided contact rubber seal against dust, mud and water splash
• 2NR: Dual outer ring snap ring grooves for axial housing locking

Triple inner ribs + single outer central rib form integrated locating structure. Cage-free full roller layout maximizes radial load capacity, supports heavy radial load plus moderate bidirectional axial thrust. Pre-filled heavy-duty lithium grease; side relubrication port enables maintenance without disassembly. Designed for low-speed heavy-load rotary units including medium crane pulleys, port lifting rollers and mining light conveyors.

Drawings and heavy-load durability test reports available on request.

1. Cage-free full roller design delivers high radial load capacity
2. Integrated rib structure prevents axial shifting under heavy thrust
3. Double PP lip seal blocks outdoor dust, rainwater and metal debris
4. Dual snap ring grooves simplify axial fixation without extra housing shoulders
5. Side grease port supports convenient on-site relubrication
6. Compact cross-section reduces hub installation space
7. Standard interchangeable dimensions for direct one-to-one replacement
8. Customizable clearance, high-temp grease, laser marking and neutral export packaging
