Timken 22218 EJW33 Spherical Roller Bearing

Applications & Specifications

Key Advantages & Design Features

Main Description

The Timken 22218 EJW33 is a high-performance spherical roller bearing designed for industrial applications where heavy radial loads, misalignment tolerance, and robust durability are required. This model features a cylindrical bore, double-row design, and an EJ cage type with W33 lubrication groove and holes in the outer ring to facilitate greasing.

Technical Specifications & Dimensions

• Inner Diameter (d): 90 mm

• Outer Diameter (D): 160 mm

• Width (B): 40 mm

• Cage Type: Steel, window-type EJ cage

• Lubrication: W33 groove and lubrication holes in outer ring to support regreasing

• Load Ratings (approximate): dynamic load ~355 kN, static load ~388 kN

• Weight: ~3.1 kg

As a double-row spherical roller bearing, the 22218 EJW33 can accommodate not only significant radial loads but also axial loads in both directions and misalignment in the shaft or housing.

Applications & Use Cases

This bearing is well suited for:

• Gear reducers, heavy gearboxes, industrial drives

• Pumps, compressors, mixers

• Rolling mills, steel mills, mining equipment

• Construction machinery, vibration equipment

• Machinery in cement, paper, power plants

In heavy industrial environments where alignment errors, vibration, and shock loads are present, the spherical roller design excels in maintaining service life and reliability.

FAQ

Q1: Will the 22218 EJW33 bearing fit my assembly?
A1: Check if your shaft is ~90 mm, your housing bore ~160 mm, and available width is ~40 mm. If these dimensions match or are within tolerance, this bearing is likely compatible.

Q2: What does “EJW33” in the designation mean?
A2: EJ refers to the cage type and construction design. W33 indicates the presence of a lubrication groove and holes in the outer ring, enabling relubrication. 33 is part of Timken’s specific variant designation.

Q3: Can it handle misalignment or shaft deflection?
A3: Yes. As a spherical roller bearing, it tolerates angular misalignment between shaft and housing without undue stress, making it suitable for demanding industrial conditions.

Q4: What loads and speeds can this model handle?
A4: It is designed to support heavy radial loads and certain axial loads both directions. Speeds depend on lubrication, temperature, and load conditions; typical references from Timken yield ~3500 rpm (grease) and up to ~4300 rpm in oil, under ideal conditions.

Q5: When can I receive this bearing if I order today?
A5: We stock this bearing in Lublin. Our Warehouse & Store: ul. Smoluchowskiego 1, building 4 has it ready, and we offer 24h dispatch - fast and efficient order processing.
