Self Aligning Ball Bearing 100x215x47mm

The NTN 1320K is a self aligning ball bearing designed for use in electrician tools and test equipment. It accommodates misalignment between shaft and housing to maintain smooth operation under load. The bearing measures 100mm inner diameter by 215mm outer diameter by 47mm width and is supplied as a single unit in a box.

Thermals noise and power draw

As a passive mechanical component the bearing generates no electrical noise and draws no power during operation. Heat generation is limited to friction within the rolling elements and is managed by the equipment's own lubrication and cooling systems. No active cooling or acoustic considerations apply to this part.

100mm inner diameter 215mm outer diameter 47mm width

These three dimensions determine whether the bearing fits the intended shaft and housing. Verify the 100mm bore 215mm outside diameter and 47mm width against your equipment specifications before purchase. Buyers needing different bore outer diameter or width measurements cannot use this part.

Questions about this item

How do I mount the 100 mm bore NTN 1320K onto a shaft and what is the common mistake?

Press the inner ring squarely onto the 100 mm shaft using a sleeve that contacts only the inner race; the frequent error is hammering the outer ring or cage, which brinells the 1320K balls.

What future service will the 1320K self-aligning ball bearing require?

Plan periodic re-lubrication through the housing grease fitting; the 47 mm wide bearing has no seals, so old grease must be purged and fresh lubricant added at intervals.

Which limit appears first when the 215 mm OD bearing runs continuously under load?

The 47 mm race width reaches its thermal limit first; sustained operation raises internal temperature until lubricant film breaks down, signalling the end of safe running.
