SPHERE-ROL Bearing SB 22205 W33 SS Precision Roller Bearing 25 X 52 X 18mm

1.Product Overview

SB 22205 W33 SS is single row self-aligning spherical roller bearing of SB 22200 series, unified metric dimension bore d=25mm, outer diameter D=52mm, overall width B=18mm, straight cylindrical inner bore design.
Suffix code explanation:

• W33: Outer ring equipped with circumferential lubrication groove + 3 oil injection holes, convenient on-site refueling without disassembly, excellent continuous lubrication & heat dissipation performance;
• SS: Double-sided integrated Nylaplate composite contact rubber seal, fully block dust, mud, metal scraps and splash cutting fluid, adapt dusty humid harsh working environments;
• SB series: Separated single row spherical roller layout, steel stamping cage separates barrel rollers evenly, strong self-aligning capacity allows up to 2° angular misalignment compensation for shaft deflection or installation offsetRegal Rexn....

Inner ring, outer ring and spherical rollers adopt GCr15 chrome bearing steel overall quenching, ultra-precision spherical raceway grinding to reduce friction noise. It bears heavy combined radial load + moderate bidirectional axial load simultaneously, widely applied to light conveyor lines, textile spinning equipment, small mixing mixers, agricultural machinery transmission shafts and general industrial light heavy-duty rotating equipment.

2.Technical Specifications

Complete installation dimension drawings, lubrication matching scheme and misalignment load durability test data can be provided upon customer request.

3.Key Advantages

1. Single row spherical roller self-aligning design, automatically compensate shaft bending, housing machining error and assembly misalignment, avoid unilateral roller peeling wear and bearing locking stagnation failure
2. W33 integrated outer ring lubrication groove with three oil holes, realize external online oil injection maintenance, no need to disassemble equipment to supplement grease, greatly reduce production line downtime maintenance cost
3. Double-sided SS composite reinforced rubber contact seals, multi-lip anti-dust & anti-mud structure, effectively isolate workshop dust, water splash and grinding metal debris, long-term maintenance-free under normal working conditions
4. Separated steel cage independent positioning spherical rollers, uniform load distribution under alternating impact radial load, stable low-vibration rotation without abnormal noise during long continuous operation
5. Compact thin-wall outline size, save equipment transmission structure space, perfect matching small light-duty industrial rotating shaft installation layout
6. Customizable options: open non-seal version without SS, C3 enlarged clearance upgrade, P5 high precision grade, OEM laser marking, high temperature resistant special grease filling

Effectively extend service life of light conveyor, textile and agricultural machinery rotating transmission assemblies in dusty workshop environments

8.FAQ

1. Q1: What do W33 and SS suffixes stand for?
   A1: W33 = Outer ring with circumferential lubrication groove and 3 oil injection holes for online refueling maintenance; SS = double-sided composite rubber contact dust/mud proof seals for harsh dusty working conditions.
2. Q2: What is the difference between SB single row and conventional 222xx double row spherical roller bearings?
   A2: SB series adopts separated single row spherical roller structure, smaller outline width, lighter weight, compact installation space; double row bearings carry larger heavy load for mining large equipment, while SB fits light-duty compact transmission shafts.
3. Q3: What misalignment can SB22205W33SS compensate?
   A3: The spherical matching surface allows maximum ±2° angular misalignment, can effectively offset shaft deflection, housing processing deviation and assembly installation offset.
