What does KHSHE204 mean?

KHSHE204 is an AMI metric cast iron tapped base pillow block unit with a narrow inner ring insert and eccentric collar locking, for a 20 mm shaft. The part number breaks down into 4 segments:

KH: Narrow inner ring ball bearing insert, eccentric collar locking, spherical outer ring. Insert part number is KH204

SHE: Housing style: cast iron tapped base pillow block. Housing part number is SHE04

2: 200 series (normal duty)

04: Bore code: 04 × 5 = 20 mm

Note: For metric mounted bearings, the bore is usually the bore code × 5 mm. Codes 00, 01, 02 and 03 are the exceptions: 10, 12, 15 and 17 mm.

Frequently asked questions

What does KHSHE204 mean?

KHSHE204 is an AMI metric cast iron tapped base pillow block unit with a narrow inner ring insert and eccentric collar locking, for a 20 mm shaft. KH = narrow inner ring ball bearing insert, eccentric collar locking, spherical outer ring. Insert part number is KH204, SHE = housing style: cast iron tapped base pillow block. Housing part number is SHE04, 2 = 200 series (normal duty), 04 = bore code: 04 × 5 = 20 mm.

What is the bore size of KHSHE204?

The bore of KHSHE204 is 20 mm.

The housing of pillow block bearing, crafted from iron, is engineered to withstand heavy-load and high-vibration conditions with the structural rigidity and dimensional stability needed to keep the overall mounted bearing assembly performing reliably over the long term.

Shaft retention is achieved through eccentric collar locking in this pillow block bearing unit, which secures the shaft reliably against moderate loads and intermittent vibration — provided the collar is rotated firmly in the direction of shaft rotation and the locking screw is fully tightened — without damaging the shaft surface.

Why choose Iron for the bearing housing?

Because this pillow block bearing is specifically designed for heavy-load and high-vibration conditions, cast iron delivers superior rigidity and dimensional stability where lighter or polymer housings are prone to deformation under load, making it a purpose-built choice for this application rather than a generic substitute.

Why does this bearing use Eccentric Collar Locking to secure the shaft?

Eccentric collar locking works by rotating an offset collar in the direction of shaft rotation until it clamps firmly around the shaft, which makes it well suited to applications where the shaft surface must remain undamaged and load distribution needs to be more even. Its main advantage over other shaft locking methods is a broader contact area that reduces shaft stress, which matters most when the application involves intermittent loads, frequent starts and stops, or softer shaft materials.
