INA F-22985.RLF Needle Roller Bearing — Drawn Cup, Open Ends

INA (Schaeffler) · F-Series Needle Roller · Drawn Cup · In stock

The F-22985.RLF is a single-row drawn cup needle roller bearing manufactured by INA (Schaeffler Group, Germany). The F-series design uses a thin-walled, hardened outer sleeve with open ends, allowing the rolling elements to run directly on a hardened shaft — this saves radial space, reduces weight, and is the standard needle-bearing choice for printing press gearboxes, textile machine spindles, and automotive transmission rebuilds.

The .RLF suffix in INA's designation system confirms a full complement of needle rollers (no cage) and a lubricated, oil-preserved finish — making the F-22985.RLF particularly well suited to slow-speed, high-load oscillating applications. If you are rebuilding a Heidelberg, MAN Roland, or Komori printing press, a Sulzer or Picanol loom, or refreshing a manual-transmission input shaft, this is the OE-grade replacement KOEED keeps ready to ship.

KOEED supplies the full F-series family (F-2xxxx through F-5xxxx) alongside the companion NK, NKS, K, and RNA drawn-cup series, plus cross-reference equivalents from SKF, FAG, NSK, NTN, and Koyo. Send a photo of your old bearing tag or the machine's parts diagram to Moritta@KOEED.COM and we will confirm fitment within 24 hours.

Key Specifications

Datasheet Highlights

• Drawn cup, open ends construction — the F-22985.RLF is a single-row drawn cup needle roller bearing with a thin-walled outer ring that is split lengthwise and pressed into a housing bore. The roller set runs directly on a hardened shaft, eliminating the need for a separate inner ring.
• Full complement of needle rollers (RLF) — unlike caged K-series or NK-series designs, the F-22985.RLF carries the maximum possible number of needle rollers inside the cup. This delivers the highest radial load capacity for the same envelope, at the cost of limiting peak speed — ideal for slow-speed, heavy-load, or oscillating motion.
• Space-saving radial profile — the cross-section is roughly half that of a comparable deep-groove ball bearing of the same bore, freeing up axial and radial real estate inside compact printing-press cylinders, loom gearboxes, and transmission housings.
• Light oil preservation, ready to install — the bearing ships oil-preserved; it can be installed as-is in most MRO scenarios and run for its full design life without re-lubrication. For flooded or grease-lubricated housings, follow the machine maker's re-lube interval.
• Cross-compatible with NK, NKS, RNA series — the F-22985.RLF shares its OD profile with the NK and NKS caged equivalents, so a switch to full-complement is a drop-in upgrade when the original NK-type has reached its load limit.
• OE-grade for printing, textile, and transmission rebuilds — INA needle bearings are the OE choice on a long list of European and Japanese machine builders, and KOEED stocks the genuine F-2xxxx through F-5xxxx range for in-place replacement of worn units.

Typical Applications

The F-22985.RLF is a general-purpose drawn cup needle bearing that shows up in dozens of MRO and rebuilder workflows. The most common applications KOEED supplies this part for:

• Printing machine maintenance — cylinder support, oscillator drives, and gripper-bar pivots on commercial and packaging printing presses (Heidelberg, MAN Roland, Komori, KBA, Bobst).
• Textile machine rebuilds — spindle support, cam followers, and take-up roll shafts on Sulzer, Picanol, Toyota, and Tsudakoma looms, plus carding-machine and ring-spinning-frame bearing replacements.
• Automotive transmission rebuilder — input shaft, layshaft, and reverse-idler gear support in manual gearboxes where OE used F-series needle bearings (BMW, Mercedes-Benz, ZF, Getrag applications).
• Hydraulic pump and motor rebuilds — needle bearings on the drive shaft of axial piston pumps and motors, where space constraints rule out tapered or cylindrical roller alternatives.
• Industrial gearboxes and planetary reducers — planet-carrier and sun-shaft support in compact gearboxes where the radial section of an F-series bearing saves significant envelope.
• General MRO — any slow-to-medium speed, high radial load application where a hardened shaft is already present in the assembly. Send our bearing selection guide a photo of the old bearing tag and we will identify the correct F, NK, K, or RNA cross-reference for you.

KOEED covers more than bearings — the same shipping lane, the same quote-within-24h response, and the same nine-brand industrial automation matrix (Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic, KEYENCE) is one RFQ away. Send your full BOM alongside the bearing request and we will quote the lot in a single email.

Warranty & Authenticity

• Genuine INA (Schaeffler Group) — the F-22985.RLF sold by KOEED is sourced through the authorised Schaeffler distribution channel. Every unit ships in sealed INA packaging with the manufacturer’s batch code on the box and on the bearing itself.
• Batch-traceable — if you need the heat-treatment certificate, the material certificate (3.1 / DIN EN 10204), or a Certificate of Conformance (C-of-C) for your quality file, request it at order time and we will include it with the shipment.
• Worldwide shipping with DHL / FedEx / UPS — typical lead time is 3–5 business days for in-stock units to most major industrial regions (NA, EU, Middle East, Southeast Asia, South America). DDP terms available on request.
• 24-hour quote turnaround — send your RFQ to Moritta@KOEED.COM on a business day and you will have stock availability and price back the same day.
• Bulk pricing for printing and textile rebuilders — if you maintain a fleet of presses or looms and consume F-series bearings on a scheduled basis, ask about a frame-contract or scheduled-release agreement.
• Not sure if F-22985.RLF fits? — photograph the old bearing tag (the metal label riveted to the cup, or the laser-etched code on the outer ring) and email it to Moritta@KOEED.COM. We will read it, identify the equivalent, and quote the genuine replacement the same day.
