2. Rolling bearing size classification according to their outer diameter size, divided into:
(1) miniature bearings ---- nominal diameter size range of 26mm below the bearing;
(2) small bearings ---- nominal diameter size range of 28-55mm bearings;
(3) small and medium sized bearing ---- nominal diameter size range of 60-115mm bearings;
(4) large bearing ---- nominal diameter size range of 120-190mm bearing
(5) Large bearing ---- nominal diameter size range of 200-430mm bearings;

4，Note issue: bearing PWKR72.2RS SKF PWKR72.2RS bearings Track Rollers PWKR72.2RS
Installation and maintenance：
From the use of perspective, to ensure that the bearing can be reliably work should note the following:
1, to improve the lubrication quality, control oil pressure, temperature and flow, strengthen the oil filter.
2, using compliant fuel and lubricants.
3, temperature control status diesel generator set, in the case of cold hot work are unfavorable. Cold
weather, diesel engine starter should be preceded by warm-up, and the hand crank to make the oil
into the friction surface.
4, bearing and journal surface quality and geometry should be strictly guaranteed.
5, the bearing clearance should be appropriate, too large an impact generator set, too small poor
lubrication, may bush-burning.
How to ensure reliable operation of bearings
From the use of perspective in general should pay attention to the following points:
1. Bearing clearance should be appropriate, too large an impact, too small to poor lubrication, may
2. Bearing and journal surface quality and geometry should be strictly guaranteed;
3. Improve lubrication quality, control oil pressure, temperature and flow, strengthen the oil filter;
4. Used in line with the provisions of fuel and lubricants.
In order to give full play to the bearing and long-term to maintain its proper performance, we must
effectively do regular maintenance (periodic inspection).
Through appropriate periodic inspection, so that early detection of failures, prevent accidents in the
first place, to improve productivity and economy is very important.
Check with the judgment
In order to determine whether the removed bearing re-use, to focus on checking the accuracy of its size,
rotation accuracy, internal clearance and with the surface, raceway, cage and ring. Large bearings because
they can not rotate by hand, pay attention to check the rolling body raceway, cage, ribs and other exterior
surface, the higher the more importance bearing inspection shall be careful.
Rolling Fever Causes and Remedy:
Bearing accuracy Low: use specified levels of precision bearings.
Shaft bending or cabinet Holes: Repair spindle or box.
Poor lubrication: use specified grade lubricating material and properly cleaned.
Low assembly quality: improve assembly quality.
Bearing housing laps: Replace worn bearings and related parts.
Axial force too: clean, align the sealing port ring clearance requirements between 0.2 ~ 0.3mm, correct
impeller balance hole diameter and verification of static equilibrium value.
Bearing damage: replace the bearings.
