Inch Bearings:
- Boundary dimensions: ANSI/ABMA Standard 19.2 |
| Tolerances | Metric Bearings:
- Normal
- Tighter run-out for bearings with designation suffix CL7C
- Bearings with designation prefix J:
- ANSI/ABMA Standard 19.1, class N (corresponds to ISO class 6X and SKF class CLN)
- Check availability of tighter width tolerance to 6X tolerance class (designation suffix CLN) or P5
- Values: ISO 492 (table 1, table 2, table 3)
- The inner ring with roller and cage assembly (cone) and outer ring (cup) with the same basic designation are interchangeable.
- The tolerance for the total abutment width T of the bearing is not exceeded if the cones and cups are interchanged.
Inch Bearings:
- Normal
- Tighter run-out for bearings with designation suffix CL7C
- Check availability of CL3, CL0 or tighter width tolerance
- Values: ANSI/ABMA Standard 19.2 (table 4)
- Deviating width tolerances for cups and cones are identified by a designation suffix (table 5). |
| Internal Clearance | Obtained after mounting, depending on adjustment against a second bearing. |
| Preload | Obtained after mounting, depending on adjustment against a second bearing. |
| Permissible Misalignment | - SKF Explorer bearings: Approximately 2 to 4 minutes of arc
- Where misalignment cannot be avoided, SKF recommends using only SKF Explorer bearings.
- The permissible angular misalignment between the inner and outer rings depends on:
- Size and internal design of the bearing
- Radial internal clearance in operation
- Forces and moments acting on the bearing
- Only approximate values are listed.
- Any misalignment increases bearing noise and reduces bearing service life. |
E-ASIA Bearing introduces High Performance Mining Tapered Roller Bearings. They are to ISO 355 standard for metric sizes, whereas for inch sizes they conform to ANSI/ABMA Standard 19.2.
Our bearings are with normal tolerances and tighter run-out with suffix CL7C, when cones and cups with the same basic designation are interchangeable, hencekeeping total abutment width T constant when interchanged.
Internal clearance is set after mounting, re-measured to the second bearing. Preloading is done after mounting, based on this measurement.
The permissible misalignment for SKF Explorer bearings is about 2 to 4 arc minutes. Misalignment can raise noise levels and lower the service life, hence the necessity for alignment.

Key Features of High Performance Mining Tapered Roller Bearings
E-ASIA Bearing's High Performance Mining Tapered Roller Bearings are especially advantageous for Mining Operations. Some of the major characteristics are:
Low friction: Specially optimized design helps in increasing pre-stress, reduction of particular wear promoting the lubricant film formation and thus reduced heat and low noise levels.
Long service life: Special raceway profiles optimize distribution of the loads and reduce stresses at roller ends under the kind of conditions that would otherwise seriously affect aligning ability and deflection.
Better operational reliability: Higher quality of the surface finish of the rollers and raceways helps them produce a hydrodynamic lubricant film more easily.
Consistent roller sizes: Rollers are precision-made close to uniform size, ensuring even distribution of the loads and perfect preloading.
Tight bearing application :Preloading one single row tapered roller bearing against another gives a tight application.
Low running-in temperature peaks :This has been achieved because of our design, which ensures that friction and wear during the running-in period are held at a minimum when correctly installed and lubricated.
Separable and interchangeable components :The bearings have separable bearing components with identical dimensions to each other, making them fully interchangeable. This simplifies mounting, dismounting, as well as inspection during maintenance.
