SKF6019Single-Row Deep Groove Ball Bearing 95 x 145 x 24 mm, Open Both Faces, CN Clearance

Product Description

What this part is

This is an SKF 6019 single-row deep groove ball bearing with a 95 mm bore, 145 mm outside diameter and 24 mm width. It is open on both faces, with no seal, shield or snap-ring groove.

Decoding the designation

The 60 series prefix identifies a single-row deep groove ball bearing in the light dimension series, and the 19 bore code gives 95 mm. The designation carries no closure suffix, so both faces are open. It carries no clearance suffix, so radial internal clearance is normal, CN. It carries no cage suffix, so the cage is pressed steel.

What these specs mean in practice

A deep groove ball bearing carries radial load and moderate axial load in both directions, and it is the highest-speed and lowest-friction of the common bearing types for a given envelope. Because both faces are open, lubrication and sealing are the responsibility of the housing rather than the bearing, which is the usual arrangement where the bearing runs in an oil bath, in a circulating oil system, or behind a separate shaft seal. CN clearance suits a shaft and housing running at similar temperatures with standard interference fits.

Quantity and configuration

Single bearing, 1 Pc. Straight bore, mounting directly onto a cylindrical shaft seat.

Fitting notes

The bearing is fitted with force applied through the ring being mounted, never transmitted across the balls from one ring to the other. An interference fit on the inner ring is normally made by even heating rather than by pressing.

Interchange guidance

Same-spec equivalents are FAG 6019, NSK 6019, NTN 6019, Koyo 6019 and Timken 6019 — the 6019 base number is common across manufacturers at 95 x 145 x 24 mm, open, CN. A 6019-2RS1 or 6019-2Z shares the envelope but adds seals or shields, and a 6019/C3 differs in internal clearance; those are related sizes rather than substitutions.
