NTN 1216 Self-Aligning Bearing

The NTN 1216 is a self-aligning ball bearing designed for electrician tool applications where shaft misalignment can occur. It suits maintenance technicians and workshop professionals who need a single replacement unit supplied in a branded box. The red finish provides visual identification in a tool kit. Buyers needing multiple bearings or a different bore size should look elsewhere.

Dimensions and Mounting

This bearing features an 80 mm bore, 140 mm outside diameter and 26 mm width for standard housing fits. The self-aligning design compensates for angular errors during installation and operation, reducing edge loading on the raceways. No lubrication specifications or sealing details are provided in the data.

Sustained Operation

Under continuous load the self-aligning geometry maintains contact distribution across the balls, limiting localised stress and heat buildup. The steel construction supports consistent rotational accuracy over extended duty cycles. No noise, vibration or temperature ratings are supplied for prolonged running conditions.

Questions about this item

How do I press the 80x140x26mm NTN 1216 bearing onto the shaft without damaging the self-aligning rings?

Use a sleeve that contacts only the inner ring and apply even force; never hammer the outer ring or the red cage, as that destroys the self-aligning function.

What replacement interval should I plan for the NTN 1216 bearing under normal electrician-tool duty?

Inspect at the 3-year parts mark; replace if radial play exceeds the maker’s limit or if the red finish shows fretting corrosion.

At what point does heat become the limiting factor for the 1216 bearing during continuous operation?

Sustained temperatures above the grease rating cause lubricant breakdown first, leading to cage wear and loss of self-alignment.
