Ball Bearing, Extended Inner Ring
Frequently Asked Questions
Q: What is an extended inner ring ball bearing and where is the BA 786 used?
A: An extended inner ring ball bearing (BA 786) features a longer inner raceway than standard designs. This bearing type is used in lift truck drive motors, pump assemblies, and load wheels where axial load distribution is critical. The extended inner ring distributes loads across a wider surface area.
Q: Which electric lift truck brands use the BA 786 extended inner ring bearing?
A: The BA 786 bearing is compatible with Crown, Toyota, Raymond, Yale, Hyster, and similar OEM electric lift trucks. These bearings are found in motor assemblies, pump housings, and transmission components. Verify equipment model and bearing cavity dimensions before ordering.
Q: What material is the BA 786 bearing made from?
A: The BA 786 is a precision ball bearing with hardened steel races and polished steel balls. Steel construction provides durability under continuous duty and load cycling. The bearing is sealed or unsealed depending on application requirements.
Q: How long does the BA 786 bearing last in service?
A: Service life depends on load conditions, lubrication, and duty cycle. Under normal lift truck operation, ball bearings typically last 3000-8000 operating hours. Inadequate lubrication, contamination, or overload reduces life significantly. Replace when noise, vibration, or heat increases.
Q: What maintenance does the BA 786 bearing require?
A: Sealed bearings require no maintenance beyond normal lift truck service intervals. Unsealed bearings require periodic re-lubrication per equipment manuals. Inspect bearings during maintenance for noise, heat, or play. Replace if damage is detected.
Q: How do I verify that the BA 786 bearing is the correct replacement?
A: The BA 786 bearing cavity dimensions must match your equipment. Provide the OEM part number, equipment model and serial number, and we will cross-reference to confirm fitment. Dimension mismatch causes improper seating and bearing failure.
