SL Full Loaded Cylindrical Roller Bearing

Name: SL Series Full Complement Cylindrical Roller Bearings
Brand: YJZY
Availability: InStock

SL full loaded cylindrical roller bearings are usually guided by two edges of a bearing ring, and the cage, roller and guide ring form an assembly, which is generally separable bearings. This kind of bearing is easy to install and disassemble, especially when the inner and outer rings are required to have interference fit with the shaft and housing.

SL Series Full Complement Cylindrical Roller Bearings

Structure & Advantages

SL series are full complement cylindrical roller bearings without cage, fitted with maximum number of rollers to achieve extreme radial load capacity. Most SL18 type bearings adopt inner ring double ribs and outer ring single rib construction, capable of bearing heavy radial load and one-way axial load for axial positioning. SL04 series are specially designed pulley bearings, available with sealing and anti-corrosion coating options. Separable design simplifies installation and inspection.

Frequently Asked Questions

What is SL full complement cylindrical roller bearing and where is it widely used?

SL series are full complement cylindrical roller bearings without cages. More rollers are assembled inside to achieve extremely high radial load capacity. SL18 series can withstand heavy radial load plus one-way axial load for positioning. SL04 are dedicated pulley bearings commonly used for crane and lifting equipment. Typical applications include steel mills, mining machinery, heavy gearboxes, conveyors and construction machinery.

What do common suffixes mean for SL bearings?

C3 = increased radial clearance; C4 = larger clearance than C3; PP = double side sealing; RR = Corrotect anti-corrosion coating; GA22 = pre-filled wide temperature lithium grease. Custom combinations like PP RR GA22 C3 are available for harsh working conditions.

Can your SL bearings fully interchange with mainstream brand bearings?

Yes. Our SL full complement cylindrical roller bearings follow ISO standard dimensions and tolerance, direct replacement for corresponding mainstream models without housing or shaft modification. Raw material and heat treatment are strictly controlled for stable heavy-load performance.

What is your lead time and stock availability for bulk SL bearing orders?

Most standard SL1822, SL1823, SL1830 and common SL04 models are in ready stock. Bulk orders can be shipped within 3-7 working days. Special suffix combinations and non-standard sizes require 15-30 days production lead time.

Can you supply SL bearings with special coatings, grease or clearance?

Yes. We support anti-corrosion RR coating, PP sealing, pre-filled GA22 grease and custom clearance C2/C3/C4/C5. Special surface treatment is available for dusty, humid and corrosive heavy-duty environments.

Category Overview

Cylindrical Roller Bearings are radial rolling bearings with cylindrical rolling elements that make line contact with raceways. They feature high radial load capacity, high rigidity, high-speed capability, and low friction.Most types can accommodate axial displacement between shaft and housing, and some structures allow carrying axial loads. They are widely used in motors, gearboxes, pumps, compressors, machine tools and other heavy‑duty rotating equipment.

Our Series Breakdown

We offer a complete range of cylindrical roller bearing series to suit different positioning and load requirements:

Series	Features	Typical Applications
NU Series	Floating bearing, free axial displacement, high radial load	Motors, fans, general machinery
NJ Series	Locates shaft in one axial direction, high rigidity	Gearboxes, reducers, machine tool spindles
NUP Series	Locates shaft in both axial directions, fixed positioning	Heavy gearboxes, compressors, pumps
N Series	Outer ring with two ribs, inner ring without ribs	General industrial transmission equipment
NF Series	Single-direction axial location, compact structure	Small‑to‑medium gearboxes and motors
RN Series	Without outer ring, fits directly into housing bore	Hydraulic pumps, construction machinery
RNU Series	Without inner ring, fits directly onto shaft	Special transmission mechanisms, compact equipment

Core Advantages

Extremely high radial load capacity and strong impact resistance
High rigidity and excellent high-speed performance
Low friction, stable operation, long service life
Allow axial thermal expansion of shaft (floating types)
Separable structure for easy installation and maintenance
Available in open, sealed and precision grades

🛠️ Typical Applications

Widely used in electric motors, gearboxes, reducers, pumps, compressors, machine tool spindles, fans, rolling mills, automotive transmissions, and other heavy‑duty industrial machinery.
