INA ZKLF2575-2RS-PE Ball Bearing D25x75mm Woodworking Machine Spare Parts

When a woodworking machine spindle starts to wander or the feed axis develops end play, the cause is often a worn axial angular contact bearing. The ZKLF2575-2RS-PE addresses this by carrying combined axial and radial loads in a double-direction arrangement. Left unchecked, such wear shows up as poor surface finish and inaccurate cuts.

This bearing has a 25mm inner diameter, a 75mm outer diameter, and a 28mm width. It is made from standard bearing steel and weighs 0.72kg. The 60-degree contact angle suits axial loading. It fits woodworking machine spindles and similar assemblies that use this size. To confirm fit, measure the shaft diameter and housing bore, and check that the mounting provides fixing holes and a lubrication hole.

Mounting requires fixing holes to secure the bearing in place. The lip seals on both sides keep dust and moisture out, which matters in a woodshop. The front-side lubricating hole lets you relubricate without disassembly. The bearing runs in temperatures from -20 to +120 °C, covering most machining conditions. Proper mounting and lubrication extend service life.

Each order includes one bearing. No customisation or special packaging is stated. When enquiring, send the machine model, the current bearing part number, and the shaft and housing dimensions. Also state the operating speed and load direction so the supplier can confirm the ZKLF2575-2RS-PE matches your application. This helps avoid a wrong-fit return.

What the specification fixes, and what it leaves to the machine:

• Axial load support — With a 60-degree contact angle, the bearing handles axial loads in both directions, which suits spindles that see thrust during cutting.
• Radial load capacity — As an angular contact bearing, it also carries radial loads, so one bearing can support combined loading in compact assemblies.
• Shaft fit check — The 25mm inner diameter matches shafts of that size; measure your shaft before ordering to confirm a proper fit.
• Housing fit check — A 75mm outer diameter means the housing bore must be 75mm; check this dimension on your machine before purchase.
• Seal protection — Lip seals on both sides keep wood dust and moisture out of the rolling elements, reducing contamination-related wear.
• Relubrication point — A lubricating hole on the front side lets you add grease without removing the bearing from its mounting.
• Secure mounting — Fixing holes allow the bearing to be bolted or located positively, which helps maintain position under load.
• Temperature range — Rated from -20 to +120 °C, the bearing suits the temperature swings of woodworking machinery without losing performance.
• Double-direction design — The double-direction bearing supports axial loads from either side, useful where cutting forces reverse direction.

What changes on the shop floor when the right part goes back in:

• One bearing for combined loads. Because it carries both axial and radial loads, you may avoid separate bearings and simplify the spindle design, saving space and assembly time.
• Seals reduce cleaning downtime. Lip seals on both sides keep dust out, so you spend less time cleaning and repacking bearings, and more time running production.
• Relubricate without disassembly. The front-side lubricating hole lets maintenance add grease in place, cutting the labour and downtime of a full teardown.
• Stable under temperature swings. The -20 to +120 °C range means the bearing keeps its clearance and performance through warm-up and cool-down cycles common in woodshops.
• Position holds under load. Fixing holes secure the bearing so it stays put when axial forces push, helping maintain cut accuracy over long runs.
• Handles reversing thrust. Double-direction capability means the bearing works whether the cutting force pushes or pulls, which suits complex machining operations.
• Predictable fit from clear sizes. With 25mm bore, 75mm OD, and 28mm width stated, you can check your shaft and housing before ordering and avoid a wrong-fit return.
• It fits the machine you already run. The ball bearing is made for woodworking machines, so it returns to the same shaft, bracket or spindle without re-machining the mounting.

Check your shaft and housing dimensions first. The bearing needs a 25mm shaft and a 75mm housing bore, and the mounting must have fixing holes. If your machine uses a different size, this bearing will not fit.

It means lip seals on both sides. These seals keep dust and moisture out of the bearing, which is important in a woodshop where fine dust is always present.

Yes, there is a lubricating hole on the front side. You can add grease through this hole without removing the bearing from its mounting, which saves downtime.

The contact angle is 60 degrees. This angle determines how the bearing shares axial and radial loads; a 60-degree angle is suited to axial loading in both directions.

The bearing is rated from -20 to +120 °C. This covers the normal operating temperatures of most woodworking machinery, including warm-up and cool-down cycles.

It weighs 0.72kg. This is useful for shipping calculations and for checking that your mounting can support the bearing.

One bearing, the INA ZKLF2575-2RS-PE. No other parts or accessories are included unless you arrange them separately with the supplier.

Send the machine model, the current bearing part number, and your shaft and housing dimensions. Also state the operating speed and load direction so the supplier can confirm the fit
