Description
SKF RNAO 25X35X26 belongs to needle roller bearing, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for RNAO 25X35X26 and any equivalents.
The SKF RNAO series is a needle roller bearing without an inner ring that runs directly on the shaft. A cage keeps the needles guided, and the thin radial section suits assemblies where space around the shaft is tight but radial load capacity still matters. MR Industrial Accessories supplies this SKF line to maintenance and purchasing teams across the United States.
Read the part number as a set of dimensions. In RNAO 25X35X17, the letters identify a bearing without an inner ring, then come bore 25 mm, outer diameter 35 mm and width 17 mm. RNAO 25X35X26 keeps the same bore and outer diameter and adds width, 26 mm instead of 17 mm. Suffixes that appear in the series point to cage, tolerance or treatment variants, so confirm the complete designation with our team before ordering.
Typical service is in metalworking, food, textile and automotive plants: pumps, compressors, gearboxes, machine tools, conveyors and power transmission drives. Because there is no inner ring, the shaft itself becomes the raceway, which keeps the assembly compact. The shaft must be hardened and ground to suit that duty.
Selection starts with the shaft: its hardness and roughness decide how well the bearing will perform. Check alignment between shaft and housing as well, since misalignment can introduce axial loads the bearing was not chosen for. Lubrication can be grease or oil, following the recommendation for the actual service conditions, and dusty or humid locations call for extra sealing protection.
Interchange needs care. Needle roller bearings without an inner ring from different suppliers can differ in tolerances, cage design and load capacity, so matching main dimensions alone is not enough. Compare the full designation and the operating conditions, or let us review them for you.
During mounting, do not strike the needles, and verify radial clearance for the application. To request a quote for the SKF RNAO series, send the complete part number by WhatsApp or email; we can also suggest equivalents and help you pick the right variant.

Frequently asked questions
- What does the RNAO designation tell me?
- It identifies a needle roller bearing without an inner ring, with a cage and guided needles, mounted directly on a hardened and ground shaft. The numbers that follow give bore, outer diameter and width.
- How do I select the correct RNAO bearing?
- Work from the shaft and housing dimensions, the radial load, the speed and the environment. Confirm shaft hardness and roughness, and check alignment. Our team can review the complete part number with you.
- Can an SKF RNAO bearing replace another brand?
- Sometimes, when dimensions and the full designation match. Tolerances and load capacity may still differ, so compare the technical data first. Ask us about equivalences.
