RUKO SLS-SPS Vapor 20,4 mm guľôčkové ložisko

Maintenance technicians and machinery operators rely on this deep groove ball bearing for smooth rotational movement in industrial equipment. The 20 mm bore fits standard shafts, while the 47 mm outer diameter and 14 mm width suit common housing dimensions.

Key specifications

• Bore diameter: 20 mm
• Outer diameter: 47 mm
• Width: 14 mm
• Seal type: 2RSR (two contact rubber seals)
• Internal clearance: C3
• Material: Bearing steel
• Cage material: Sheet steel
• Basic dynamic load rating: 12.7 kN
• Basic static load rating: 6.55 kN
• Limiting speed (grease lubrication): 9000 rpm
• Operating temperature range: -30 to +100 °C
• Precision class: P0

Why choose it

The 2RSR rubber seals keep lubricant in and contaminants out, extending service life in dusty or wet environments. C3 internal clearance accommodates thermal expansion and slight misalignment, reducing the risk of premature failure. Greased for life, it requires no relubrication in normal use.

Ideal use cases

• Electric motors and pumps
• Conveyor rollers and fans
• Agricultural machinery and gearboxes

Good to know

Single row design handles radial and moderate axial loads. Bearing steel construction ensures durability under continuous operation.
