Description

NTN 31308 Tapered Roller Bearing, Single Row, 40 x 90mm — NTN. BOLTON SKU 66032.

Add this item to your RFQ basket to request pricing, lead time and documentation requirements (e.g. CoC, datasheets or test reports where applicable to your order).

Metric tapered roller bearings are numbered so that the last two digits give the bore in five-millimetre steps: 08 in 31308 corresponds to the 40 mm bore. The 313 series prefix sets the width and taper proportions, and single-row types of this kind carry combined radial and axial load in one direction.
