SL183022 Full Complement Cylindrical Roller Bearing 110x170x45mm Semi-Locating Open Heavy Load Bearing

1. Product Overview

SL183022 is single row cage-free full complement cylindrical roller bearing, dimension 110×170×45mm, semi-locating structural design with two inner ribs and one outer rib. Max quantity rollers installed without cage to achieve maximum radial load capacity. Open structure supports side re-lubrication; semi-locating feature limits shaft axial displacement in single direction, compatible with heavy low-to-medium speed equipment. Equivalent model NCF3022, widely applied to textile machinery, wind power auxiliary parts, heavy conveyors, mining equipment and paper industry calender rollers.

3. Core Advantages

• Cage-free full roller layout, ultra-high dynamic & static radial load capacity
• Semi-locating rib structure controls unidirectional axial movement, simplify shaft layout
• Open end design allows regular supplementary lubrication to extend service life
• Thickened raceway and roller surface, strong wear resistance for continuous heavy load operation
• Compact outer dimension reduces overall equipment weight and installation space
• Standard interchangeable size, cross replaceable with NCF3022 series bearing
• Custom high-temperature tempering, large clearance grade and outer ring laser marking available

4. Application Scenarios

• Textile industry: Large spinning frames, textile calender heavy rollers
• New energy: Wind turbine auxiliary transmission, fan heavy spindle supports
• Conveying & mining: Mine heavy belt conveyors, stone crusher auxiliary shafts
• Paper machinery: Paper making drying rollers, calender rotating assemblies
• General heavy machinery: Large gearbox low-speed heavy load positions

Fit OEM assembly and aftermarket replacement of heavy radial load low-medium speed industrial equipment.
