Frequently Asked Questions

Q: What is the difference between the 51111, 51112, 51113, 51114, and 51115 bearing models?

A: The primary difference is physical size. Each model number corresponds to a different set of dimensions (inner diameter × outer diameter × height): 51111 is 55×78×16 mm, 51112 is 60×85×17 mm, 51113 is 65×90×17 mm, 51114 is 70×95×18 mm, and 51115 is 75×100×19 mm. All five share the same ABEC-1 grade flat thrust ball bearing design and bearing steel construction.

Q: What does ABEC-1 grade mean for a thrust ball bearing?

A: ABEC-1 (Annular Bearing Engineers' Committee Grade 1) is the standard industrial tolerance class for bearings. It indicates the bearing meets defined dimensional and geometric accuracy standards, making it suitable for general-purpose machinery, conveyor systems, automotive components, and similar applications where high precision is not the primary requirement but reliable performance is essential.

Q: How many bearings are included in each purchase?

A: Each listing includes 1 piece (1 pc per lot). If you require multiple bearings, please adjust the quantity at checkout accordingly.

Q: Are these bearings compatible with both metric and standard shaft sizes?

A: These bearings use metric dimensions (millimeters). Please verify the inner diameter, outer diameter, and height specifications against your application's shaft and housing dimensions before ordering to ensure the correct fit.
