The 23934KW33 is a double row spherical roller bearing with a 170 mm bore, 230 mm outer diameter and 45 mm width. The rollers run on a spherical raceway in the outer ring, so the bearing self-aligns and keeps full roller contact while carrying heavy radial load and a moderate axial load in either direction.
Typical uses are steel plants, vibrating screens. Every bearing is dimensionally inspected to ISO 492 before dispatch, and the 23934KW33 can be supplied under neutral packing, custom packaging or a full private label set.
Product Description
The 23934KW33 is a double row spherical roller bearing with a 170 mm bore, 230 mm outer diameter and 45 mm width. The two rows of barrel shaped rollers run on a common spherical raceway in the outer ring, so the bearing keeps full roller contact even when the shaft and the housing are not perfectly aligned. This self-aligning behaviour absorbs shaft deflection and mounting error that would otherwise shorten the life of a rigid bearing.
That combination of self-alignment and a high radial load rating makes the 23934KW33 a practical choice for steel plants, vibrating screens, where shock loads, contaminated surroundings and small alignment errors are normal operating conditions. It carries heavy radial load together with a moderate axial load in either direction. Its tapered bore is designed for mounting with an adapter sleeve or a withdrawal sleeve, so the bearing can be locked onto a plain shaft without a shoulder. If your duty point runs at very high speed or in an extreme-temperature environment, confirm the selection with us before ordering.

| Item | Guidance |
|---|---|
| Mounting | Press or heat fit the bearing through the ring that carries the interference. For a tapered bore, drive the bearing up the adapter sleeve until the internal clearance reaches the value the application calls for, then lock the sleeve nut. |
| Self-aligning capacity | The spherical outer raceway compensates angular misalignment between shaft and housing, so the bearing tolerates shaft deflection under load |
| Axial load | Carries a moderate axial load in either direction on top of its high radial capacity; do not use it as a pure thrust bearing |
| Lubrication | W33 — the outer ring carries a lubrication groove and three oil holes, so grease or oil reaches the roller path directly |
| Storage | Keep in the original packaging, dry and free from vibration |
| Operating limits | Not intended for extreme temperature or severe shock loading — confirm the duty point before selection |
The 23934KW33 has a 170 mm bore, a 230 mm outer diameter and a 45 mm width, with a tapered bore 1:12. It is a spherical roller bearing supplied under the Nexans Bearing brand.
Both rows of rollers run on a single spherical raceway in the outer ring, so the 23934KW33 self-aligns and keeps full roller contact when the shaft deflects or the housing is not perfectly square to the shaft. This is the main reason spherical roller bearings are chosen for heavy equipment where alignment cannot be held rigidly.
MOQ depends on the product line and the packaging type. Standard stock items can be supplied in small trial quantities, so tell us the quantity you need and we will confirm it against current stock.
Yes. We provide custom packaging, laser marking on bearing rings, neutral packing and full private label sets. Lead time and MOQ for custom orders are negotiable.
