The Timken 241 Series is the widest cross-section spherical roller bearing in Timken’s metric lineup — double-row, self-aligning, and engineered for applications where combined heavy radial and continuous axial thrust push other series past their limits. Section height and width both exceed 240, 232, and 231, yielding the highest dynamic axial capacity in the family. Common on vibrating screens, crushers, heavy conveyor pulleys, continuous casting machines, rolling-mill stand rolls, and large gearbox output shafts under extreme shock and sustained thrust.

• Construction: Double-row self-aligning, widest section — compensates for shaft misalignment up to 1º while absorbing heavy radial and axial load simultaneously.
• Cage options: Both steel stamped window (“EJ” suffix) and brass machined finger (“EM” suffix) variants — EM preferred for shock-heavy, high-temperature, or vibration-intensive service.
• Bore types: Both cylindrical (straight) and tapered (“K” suffix) bore variants — tapered bore mounts on an adapter/withdrawal sleeve for easy installation on smooth shafts.
• Relubrication: W33 feature (oil groove + three holes in the outer ring) standard on most variants; W841 and similar feature packs on specialty builds.
• Clearance classes: C0, C2, C3, C4, and C5 — C3/C4 recommended for elevated temperature and interference-fit mounts; C5 available on select large variants.
• Bore range: 110 mm – 480 mm (4.33 in – 18.90 in).
• Width range: 69 mm – 308 mm — widest in the metric spherical roller family.
• Typical applications: Vibrating screens, primary and secondary crushers, heavy conveyor pulleys, continuous casting, rolling-mill stands, mining haul gearboxes, ship propulsion thrust bearings.

Why 241 vs. 240: The 241 has a wider cross-section and higher axial capacity than the 240 — choose 241 when combined radial plus heavy axial thrust or severe shock is present; choose 240 for pure radial duty in the same bore range.
