FAQ

What is the feature of 23000 series spherical roller bearings?

23000 series is narrow section spherical roller bearing. It has smaller width compared with 231/223 series under same bore size, perfect for machines with limited installation space.

What does K suffix stand for on 23000 bearings?

K means 1:12 tapered inner bore, mounted with adapter sleeve, convenient for installation and disassembly.

What is W33 for 23000 spherical roller bearing?

W33 stands for circumferential grease groove and 3 lubrication holes on outer ring, supports re-lubrication during continuous operation.

Do you support OEM and custom export packaging?

Yes, we support OEM with YJZY brand logo, neutral export packaging and customized marking for bulk importers and machinery distributors.

Category Overview

Spherical Roller Bearings are double-row, self-aligning rolling bearings with barrel-shaped rollers and a spherical outer raceway. They are specially designed to accommodate heavy radial loads, impact loads, and moderate axial loads, while automatically compensating for shaft deflection and mounting misalignment.With exceptional rigidity, durability, and low maintenance requirements, they are widely used in heavy industrial machinery operating under severe conditions.

Our Series Breakdown

We offer a complete range of spherical roller bearing series to meet different load, size and application needs:

Series	Features	Typical Applications
222 Series	Compact design, medium load capacity, good self-aligning performance	General heavy machinery, reducers, fans, pumps
223 Series	Enhanced load capacity, wider cross-section, strong shock resistance	Crushers, vibrating screens, conveyors, mining equipment
230 Series	Low cross-section, high stiffness, suitable for restricted radial space	Large gearboxes, paper machines, industrial transmission
240 Series	Extra wide cross-section, ultra-heavy load capacity, long service life	Large-scale crushers, mills, metallurgical equipment
231 Series	High load, large size, good axial load resistance	Heavy reducers, rolling mills, large fans
241 Series	Super heavy-duty, large dimensions, high reliability	Metallurgical machinery, mining equipment, large crushers

Core Advantages

Excellent self-aligning ability to compensate shaft misalignment
