Product detailed description

Bearing - NA 40 V ZKL

NA 40 V ZKL full-complement needle roller bearing

NA 40 V ZKL is a radial needle roller bearing with an inner ring and a full complement of needles without a cage. The designation is associated with the dimensionally corresponding NKIS40 type. A high number of rolling elements increases radial load capacity while retaining compact dimensions.

Key features

• dimensions: 40 × 65 × 22 mm,
• inner ring for a 40 mm shaft,
• full-complement V design without a cage,
• high radial load capacity relative to bearing cross-section,
• best suited to low or moderate speeds and oscillating motion.

Typical applications

Typical uses include gearboxes, agricultural and construction machinery, pivot points and other compact arrangements exposed to high radial loads. The inner ring is advantageous when the shaft surface cannot serve directly as a raceway.

Mounting and lubrication

Provide clean, accurate seating surfaces, suitable radial lubrication and adequate guidance of related components. A full-complement design has more friction than a caged version, so the application’s permissible speed and lubrication intervals must be observed. The bearing is intended mainly for radial forces; provide axial guidance separately.

Replacement check: before ordering, compare the complete designation NA 40 V ZKL, the 40 × 65 × 22 mm dimensions, inner ring and full-complement design with the original part.
