Series Naming Rule Explanation

Suffix P = Pillow Block; S = Short Low Slim Base (short foot, low center height, compact footprint for tight installation clearance)
Middle code = Insert bearing locking & inner ring structure

ES (UES) = UE concentric split collar insert (wide inner ring, 360° uniform clamping, bidirectional rotation)
ES (LES) = LE double-side symmetric extended inner single eccentric insert (triple heavy mud seal, unidirectional muddy outdoor sites)
YS (UYS) = UY single-side extended inner single eccentric insert (double-lip reinforced seal, medium vibration unidirectional)
YS (LYS) = LY economical single-side extended inner single eccentric insert (light dust seal, budget light-medium load indoor equipment)

Full complete unit codes:

UESP = UES Series (UE concentric split collar insert + S short low pillow block housing)
LESP = LES Series (LE dual extended eccentric insert + S short low pillow block housing)
UYSP = UYS Series (UY single extended eccentric insert + S short low pillow block housing)
LYSP = LYS Series (LY economical single extended eccentric insert + S short low pillow block housing)
