Product detailed description

30304 A ZKL is a separable single-row tapered roller bearing. Its tapered rollers and angled raceways carry high radial loads together with axial load in one direction. The dimensions are 20 × 52 × 16.25 mm (bore × outside diameter × total width).

Key features

  • High load capacity: suitable for combined radial and axial loading.
  • One-direction axial guidance: one bearing carries axial force in one direction; an opposed bearing is normally used for guidance in both directions.
  • Separable design: the inner-ring roller assembly can be separated from the outer ring, simplifying installation.
  • Adjustable arrangement: when mounted as a pair, clearance or preload must be set correctly for the machine design.

Typical applications

Gearboxes, axles, hubs, industrial drives, agricultural and construction machinery and other assemblies subject to combined loading.

Installation and selection

Keep the cone and cup as the correct matched components and install on clean seating surfaces. Apply force only through the ring being fitted. For replacement, verify the complete 30304 A designation, 20 × 52 × 16.25 mm dimensions, clearance or preload, accuracy and operating conditions; the A suffix is part of the manufacturer's exact designation.
