FCB-25 / FCB25 / HFL2530 Lock / Drawn Cup Roller Clutches / Needle Bearing Rollers 25*32*30mm

1. Product Overview

FCB-25, FCB25 and HFL2530 are identical metric integrated one-way drawn cup needle clutch bearings with unified dimension Fw=25mm, outer diameter D=32mm, overall width C=30mm. FCB-25 and FCB25 are two different marking formats of the same product; HFL2530 is the standard industry designation for this integrated overrunning bearing unit.

Different from simple HF series single clutch rollers without side support, this HFL/FCB type combines central one-way locking clutch mechanism plus two side needle roller supporting assemblies in one integral drawn cup shell. Stainless steel leaf springs drive inclined needle rollers to realize unidirectional torque transmission and anti-reverse self-locking, meanwhile the bilateral needle groups bear continuous radial load simultaneously.

Outer shell adopts stamped high-strength steel, needle rollers and inner matching race surface use GCr15 bearing steel with overall quenching treatment. Open both ends design facilitates regular re-lubrication. Only fit 25mm quenched mirror finished shaft, widely used for small reducers, textile machinery, packaging conveyors, printing equipment, household appliance transmission and light industrial anti-reverse overrunning drive assemblies.

3. Key Advantages

1. All-in-one integrated structure combining one-way clutch + bilateral radial needle supports, no extra separate needle bearings required, greatly simplify equipment transmission layout and reduce part stock varieties
2. Built-in stainless steel leaf spring locking mechanism, stable one-way self-locking performance, reliable anti-reverse function under frequent start-stop and reciprocating torque load
3. Double-side dense needle roller layout provides strong radial load capacity, uniform stress distribution, effectively avoid unilateral eccentric wear during continuous operation
4. Thin integral drawn cup press-fit installation design, directly pressed into housing interference hole without positioning sleeves or snap rings, cut assembly labor cost
5. Uniform ultra-precision grinding needle rollers and inclined raceway surface, low friction, stable high-speed rotation and long contact fatigue service life
6. Customizable options: single/double RS rubber dust seals, stainless steel anti-rust outer cup, OEM laser marking, food-grade low-temperature special grease filling

Effectively reduce transmission system failure rate and extend service life of anti-reverse overrunning mechanical assemblies

8. FAQ

• Q1: What is the difference between FCB-25, FCB25 and HFL2530?
  A1: FCB-25 and FCB25 are two simplified marking formats; HFL2530 is the global standard model designation, all three share identical dimensions, structure, torque and load parameters, fully interchangeable.
• Q2: What is the core structural advantage of HFL/FCB series vs HF series one-way bearings?
  A2: HFL/FCB integrates bilateral radial needle support on both sides of central clutch, can bear radial load independently without matching extra HK needle bearings; HF only contains single clutch rollers without side support.
• Q3: Can this bearing realize anti-reverse self-locking function?
  A3: Yes, built-in stainless steel leaf spring pushes inclined needles to wedge between shaft and outer shell, automatically locks reverse rotation and transmits torque in single direction.
