Understanding Pillow Block Roller Bearing Fundamentals

Pillow block roller bearings (PB 205 series) account for 38% of industrial rotational support systems globally. These units combine cast iron housing with tapered roller bearings, achieving radial loads up to 24kN and axial loads of 15kN. The standard linear pillow block bearings feature:

  • ±0.01mm radial runout tolerance
  • IP55 corrosion resistance rating
  • 120°C continuous operating temperature

Technical Superiority in Heavy-Duty Operations

Field tests demonstrate 72% longer service life compared to flange bearings in conveyor systems. Advanced sealing systems reduce lubricant consumption by 40% while maintaining:

  1. 92% efficiency at 3,600 RPM
  2. Vibration levels below 4.5mm/s RMS
  3. 0.85μm Ra surface finish on raceways

FAQS on pillow block roller bearing

Q: What are the primary applications of pillow block roller bearings?

A: Pillow block roller bearings are used to support rotating shafts in machinery, such as conveyors, agricultural equipment, and industrial fans. They provide easy mounting and alignment while handling radial loads.

Q: How does a pillow block 205 differ from other pillow block models?

A: The "205" in pillow block 205 refers to its specific bearing insert size (25mm bore diameter). It is designed for medium-duty applications and compatible with 25mm diameter shafts.

Q: Can linear pillow block bearings handle axial loads?

A: No, linear pillow block bearings are optimized for linear motion systems and primarily support radial loads. For axial loads, additional thrust bearings or specialized designs are required.

Q: What maintenance is required for pillow block roller bearings?

A: Regular lubrication and periodic inspection for wear or contamination are essential. Sealed variants may require less frequent maintenance depending on operating conditions.

Q: How do I choose between standard and linear pillow block bearings?

A: Use standard pillow block bearings for rotational shaft support, and linear versions for straight-line motion systems like sliding doors or CNC rails. Consider load direction and movement type when selecting.
