The MRC (SKF) 100KSZZ is a miniature-to-small-size deep groove ball bearing intended for compact machinery, electric motors, instrumentation, mechanical assemblies, and other applications where a conventional heavier bearing series would occupy excessive space.

The 100-KS Series is characterized by an Extra Light cross-section, providing a relatively small outside diameter and width for its 10 mm bore.

Dimensions:

Bore Diameter: 10.000 mm

Outside Diameter: 26.000 mm

Width: 8.000 mm

Approximate inch dimensions:

0.3937 × 1.0236 × 0.3150 in

The bearing uses a conventional single-row deep groove raceway, allowing it to carry primarily radial loads while also supporting moderate axial loads in both directions.

The ZZ portion of the designation is associated with protection on both sides, typically using metal shields in conventional bearing nomenclature. Because historical MRC designations can vary by series and production period, the exact closure construction of the specific 100KSZZ should still be verified from the original bearing or MRC drawing where critical.

Raceway Type: Deep Groove

Series Characteristic: Extra Light / compact cross-section

Basic Dynamic Radial Load Rating (C): 4,620 N / 4.62 kN / approx. 1,040 lbf

Basic Static Radial Load Rating (C₀): 1,960 N / 1.96 kN / approx. 440 lbf

Load Capability: Primarily radial load with moderate axial-load capability in both directions

Closure Type: Protected on both sides; commonly double-shielded in ZZ-type execution

Suffix ZZ: Typically associated with two metal shields; verify actual MRC 100KSZZ construction if exact closure material is critical

Lubrication: Generally grease-retaining protected configuration; verify actual lubricant specification

Maximum Speed: Approximately 19,000–30,000 rpm, depending on closure, lubrication, internal clearance, load, shaft/housing fit, and temperature

Internal Clearance: Verify original MRC specification

Cage: Verify actual MRC 100KSZZ construction

Temperature Range: Depends on lubricant, cage, closure material, fit, and operating conditions

Shaft Fit: Nominal 10 mm shaft; verify tolerance and interference

Housing Fit: Nominal 26 mm housing bore; verify housing tolerance

Installation Consideration: Confirm the full 100KSZZ designation, closure type, clearance, lubrication, operating speed, shaft fit, and housing fit before installation

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• MRC 100KSZZ
• MRC 100 KS ZZ
• 10x26x8 mm Deep Groove Ball Bearing
• 100-KS Extra Light Bearing
• Double-Shielded 10 mm Bore Bearing
• 26 mm OD Ball Bearing
• Compact Industrial Ball Bearing
• High-Speed Small Ball Bearing
• Legacy MRC 100-KS Bearing
• Extra Light Deep Groove Bearing

A bearing with the same 10 × 26 × 8 mm dimensions should not automatically be treated as an exact replacement unless its:

• Internal geometry
• Closure
• Internal clearance
• Cage
• Lubrication
• Dynamic/static load ratings
• Speed capability
• Shaft fit
• Housing fit

also match the original application.
