SL Full Complement Cylindrical Roller Bearings

Bearing Features

1. Ultra-high radial load capacity: No cage design, with 20%-30% more rollers than caged bearings, maximizing rolling elements in the same space2. High motion accuracy: Inner ring often with three ribs, outer ring with middle or double ribs, rollers guided by inner ring ribs3. Stable structure: Some double-row models fix two-part inner rings with lock rings to ensure structural stability4. Suitable for low-speed, low-temperature heavy-duty conditions with good lubrication and high housing cleanliness

Bearing Classification

1. By row count: Single-row (SL18/SL19 series), double-row (SL04/SL1850 series)2. By structure: NJ…V, NUP…V, RNU…V etc.; NU/N type allows axial displacement, NJ/NF type for one-way positioning, NUP type for two-way positioning

Application Scope

Metallurgical machinery, mining equipment, port crane pulley blocks, precision machinery, high-load equipment in compact sizes and other low-speed heavy-duty scenarios
