DOUBLE-ROW BALL BEARINGS 43XX

Type: Double-row deep groove radial ball bearings. Two rows of balls in cylindrical raceways, reinforced PA66 polyamide or pressed steel cages.

Features: For the same outside diameter and bore as single-row bearings, they are slightly wider with a significantly higher load capacity. High osculation between balls and raceways.

Load capacity: Approximately double that of a single-row bearing (series 62, 63) with the same diameters. Reduces the need for larger bearings.

Protection: Open without seals, with 2Z shields, or sealed 2RS. Nitrile rubber seals protect the lubricant.

Lubrication: Periodic greasing for open versions. Sealed versions are pre-greased for life.

Specifications: Medium-high radial capacity, low friction, medium speeds, temperatures -30°C to +80°C, reduced clearance C2 as standard.

Applications: Motors, transmissions, gearboxes, fans, pumps, agricultural machinery, systems with moderate to high radial load.

Benefits: Double capacity with compact dimensions, simple construction, various protections, moderate cost.
