This heavy-duty clutch (aka a hold-back clutch) is good for high torque operations and ensures motion freezes in place. Bore (ID) sizes: 15 to 40 mm. (0.59 to 1.73 in)

No built-in ball bearing support. Has no RPM limits & Supports high torque needs: 609 to 14,060 Nm. Bore (ID) sizes: 38.09 to 220 mm (1.499 to 8.66 in)

The best protection for your bearing. Easy to install with a simple “drop-in” next to your bearing. No added space needed. CF seals offer 100% sealing efficiency against splashing liquids.

Additionally, bearings also have a clearance value. This provides the bearing room for expansion between the bearing races and will add a small amount of play between the two rings.

Reduce your chances of a premature bearing failure or machine malfunction by using our quick-and-easy proprietary tolerancing calculators:

Most bearings have their references numbers engraved on the bearings themselves, but these often rub off over time and so it may be necessary to measure the bearing yourself, as described below.

Using our free web-based automatic tolerance calculators should give you the tolerance analysis you’ll need for your machined shaft and housing.

On applications where the shaft is rotating, using a press fit will prevent the bearing’s inner ring from rotating, relative to the shaft. If the inner ring rotates separately from the shaft, then micro-fretting and premature bearing failure could occur.

You can measure the dimensions of a bearing by using a vernier calliper like the one below or measuring accurately with a ruler.

Thermal Range Calculator: Calculates the thermal expansion effects due to operating temperatures to find the right shaft and housing tolerances for the application.

Machined parts and components all have tolerance standards when manufactured. These standards produce a consistent, uniform product.

Using our thermal range calculator, you can manipulate the shaft and housing tolerances to automatically find the best tolerance for the resultant fit.

Includes built-in ball bearing support. Supports MEDIUM loads & low to medium torque capacity: 53 to 267 Nm. Bore (ID) sizes: 17 to 40 mm (0.669 to 1.57 in)

Bearings have tolerance standards for the inner diameter (ID) and the outer diameter (OD). Machined shaft and housings also have tolerance standards on their parts that range around 10µm.

If you’d like a custom bearing performance analysis or tolerance analysis, fill out our contact form or give us a call today at 800.323.5725 for more information.

An example of where a larger clearance is required is if a bearing is likely to get hot. The heat needs room to escape otherwise there is a risk of bearing failure.

H8 tolerance

Once you have determined the dimensions of your bearing, you can use our bearing search tool to find the correct bearing.

For high-speed applications, the centrifugal force could cause the inner ring to expand and lift off the shaft which could lead to drastic machine malfunctions and a decrease in bearing life. Increasing the press-fit on the bearing and shaft would help counteract this scenario.

Interference fit

Automatic Tolerance Calculator: Ensures your shaft and housing are (or will be) machined within the recommended tolerances.

Includes built-in ball bearing support. Supports HEAVY loads & has a high torque capacity: 53 to 588 Nm. Bore (ID) sizes: 10 to 60 mm (0.393 to 2.362 in)

Other tolerance recommendations such as shaft and housing concentricity, surface roughness and runout and are located on pages 70-72 of the GMN Bearing catalog.

Finding the right shaft OD to match the inner ring (or ID) of the bearing and the correct housing ID to match the outer ring (or OD) of the bearing, produces a resultant fit.

Fit tolerance

Designed with grooves in the outer ring to offer more protection (than our L-type seal) against contamination and direct spray liquids. Liquid gets pushed out through outer grooves when in rotation.

We recommend using a slip fit on the housing so bearings can move axially for spring preloads or to absorb thermal expansion.

Bearinghousing tolerance

However, if the slip fit is too large then micro-fretting between the bearing outer ring (OD) and the housing could occur. In extreme cases, the bearing orbiting geometric center could also result.

It’s important to know about tolerances because, during operation, temperatures rise causing the bearings, shaft and housing to expand, along with their respective tolerances. Be prepared for these changes when machining a shaft and housing unit so that you are choosing the correct bearing and fit for your application.

Our GMN Gap Seals are plastic and a great choice for washdown applications, such as food conveyors and food manufacturing facilities

Dec 6, 2023 — 1. Strange Noises If you hear a consistent, rhythmic noise that sounds like growling or humming, it's a strong indicator of a bad bearing.

In rotating shaft applications, we recommend a press-fit between the shaft and the inner ring (ID) of the bearing and a slip-fit between the housing and the outer ring (OD) of the bearing, when in use.

Our ABEC 7, P4+ precision class of bearings allow for tighter resultant fits for those doing final grinding / lapping just before assembly. We provide the exact bearing inner diameter (ID), outer diameter (OD) and width (W) value deviation from nominal for each specific bearing which will also give you a tighter resultant fit.
