What is pinion bearing?

What is pinion bearing?

In drive differentials, pinion bearings help the smallest gears in the differential work smoothly. Differentials are made up of a series of gears and cogs, and it is the smallest gears that allow one wheel to safely rotate faster than the other. Pinion Nut. Pinion nuts secure the driveshaft yoke to the pinion gear.

How do you order bearing sizes?

All bearings will have an inner diameter (ID), an outside diameter (OD) and width (W). Bearings are sometimes referenced by these dimensions, in that order: ID x OD x W.

Why do bearings need preload?

An axial preload ensures constant contact between the ball complement and bearing races reducing or eliminating both modes of play. Properly preloading a bearing can increase its life and eliminate the vibration and noise that results from specified clearance, manufacturing precision, and wear.

How to measure and choose the correct bearing size?

Once you measured your bearing, you can use our search to find the correct bearing size. e.g. Inside Diameter: 25mm; Outside Diameter: 52mm; Width: 15mm – Bearing Type: 6205 Once you know the bearing you need based on size, you can then choose further options:

What is the first digit of inch bearings?

Thus, we can easily identify now that in case of bearing 6305ZZ, the first digit ‘ 6‘ means the bearing type is ‘Single row deep groove ball bearing’. In case of Inch bearings, the bearing’s first digit will be ‘R’.

Where is the series number on a ball bearing?

Each combination of these measurements corresponds to a series number, usually located directly on the bearing. Ball bearing size charts are widely available, and can be used to find the measurements of a specific bearing.

How big is a 6000 series ball bearings?

6000 Series Size Inner Dimension (in) Outer Dimension (in) Width (in) Weight (lb) 6000 10 26 8 0.042 6001 12 28 8 0.048 6002 15 32 9 0.068 6003 17 35 10 0.088

What are the dimensions of a ball bearing?

Ball bearing size charts are widely available, and can be used to find the measurements of a specific bearing. Series 6200 and 6300 are the most commonly used, and typically range from 10 x 30 x 9 mm (.394 x 1.181 x .354 in) to 150 x 320 x 65 mm (5.906 x 12.598 x 2.559 in).

How to determine bearing shaft and housing fit?

In this situation, your inner ring will rotate, the applied load direction will be constant, and the outer ring is stationary. Let’s get more specific and use the following measurements: the shaft is 20mm with a 6204 ball bearing (0.787402” x 1.85039”) (I.D. x O.D.).

Each combination of these measurements corresponds to a series number, usually located directly on the bearing. Ball bearing size charts are widely available, and can be used to find the measurements of a specific bearing.

What should the clearance be between bearing bore and shaft?

For these conditions, we recommend an interference fit between the shaft and bearing bore. The level of interference will increase for heavier loads. When shaft conditions are stationary, and the radial load is constant, a moderate clearance fit between the shaft and bearing bore is an option. Selecting the Proper Housing Fit
