The Timken 213 Series is a small, compact, double-row, self-aligning spherical roller bearing built around a steel stamped window cage (“EJ” suffix). Engineered for light-to-medium-duty industrial applications where space is tight and loads are moderate — small pumps, fans, material-handling equipment, electric motors, and compact gearbox sections — the 213 Series delivers Timken’s self-aligning geometry in a smaller-cross-section package than the heavier 222/223/230/231 Series.

• Construction: Double-row self-aligning — compensates for shaft misalignment up to 1º under load.
• Cage: Steel stamped window (“EJ” suffix) — lightweight, efficient, cost-effective for moderate loads and standard operating temperatures.
• Bore types: Both cylindrical (straight) and tapered (“K” suffix) bore variants are available — tapered bore mounts on an adapter or withdrawal sleeve for easy installation on smooth shafts.
• Relubrication: W33 feature (oil groove + three holes in the outer ring) allows in-service regreasing without disassembly.
• Clearance classes: C0 (Normal), C2, C3, and C4 — select C3 or C4 for elevated temperatures or interference fits; C2 for tight-tolerance precision mounts.
• Bore range: 25 mm – 100 mm (0.98 in – 3.94 in).
• Typical applications: Small pumps, fans and blowers, electric motors, compact conveyors, gearbox sections, material-handling equipment, textile machinery.

Why 213 vs. 222: The 213 has a smaller cross-section and lower load ratings than the 222 Series — choose 213 when space is constrained and loads are moderate; choose 222 for heavier radial duty in the same bore range.
