FAG 634-2Z-HLC 1 Row Ball Bearing - 4 mm ID, 16 mm OD

This ball bearing is a single-row deep-groove unit designed for miniature rotary applications requiring sealed protection and a Compact form. It operates across a wide temperature span and supports high-speed rotation with a steel construction for rings, balls and cage. The bearing is intended for installations where a parallel bore and a flange outside diameter match specific shaft and housing requirements.

• 53,000r/min limiting speed increases rotational capability
• 1.84kN dynamic load capacity handles varying radial forces
• 671N static rating resists brinelling under static loads
• CN internal clearance reduces axial play for precision operation
• Steel sheet cage ensures dimensional stability at temperature

• Suitable for high-speed miniature motors in instrumentation
• Used with precision spindles in small-scale machining
• Ideal for Compact office equipment requiring sealed bearings
• Can be used for micro-gearboxes where space is limited
• Used for handheld devices needing low-maintenance rotation

The bearing functions between -30°C and 120°C.

A steel sheet cage is used to provide strength and dimensional consistency at elevated temperatures.

Minimum shaft shoulder diameter is 6.4mm and maximum housing shoulder diameter is 13.6mm.

Maximum fillet radius is 0.3mm and minimum chamfer dimension is 0.3mm.

The closed ends with shields reduce ingress, aiding operation in environments with light particulate presence.
