Series Naming Rule Explanation
Suffix U = Extra Long Slotted Take-Up Housing: Extra long sliding adjustment slot, larger linear travel range for heavy belt/chain tension fine-tuning, thicker reinforced cast iron for heavy shock loads; compared with T-type short take-up base, U-type has double adjustment stroke.
Middle code = Insert bearing locking & inner ring structure:
EU (UEU) = UE concentric split collar insert (wide inner ring, 360° uniform clamping, bidirectional rotation)
EU (LEU) = LE double-side symmetric extended inner single eccentric insert (triple heavy mud seal, unidirectional severe muddy outdoor sites)
YU (UYU) = UY single-side extended inner single eccentric insert (double-lip reinforced seal, medium vibration unidirectional)
YU (LYU) = LY economical single-side extended inner single eccentric insert (light dust seal, budget light-medium load indoor equipment)
KU+H (LKU+H) = UK 1:12 tapered bore insert + H split adapter sleeve (smooth unthreaded shaft, zero shaft scratch)
Full complete unit codes:
UEU = UEU Series (UE concentric split collar insert + U extra long stroke take-up housing)
LEU = LEU Series (LE dual extended eccentric insert + U extra long stroke take-up housing)
UYU = UYU Series (UY single extended eccentric insert + U extra long stroke take-up housing)
LYU = LYU Series (LY economical single extended eccentric insert + U extra long stroke take-up housing)
LKU+H = LKU+H Series (UK tapered bore insert + H sleeve + U extra long stroke take-up housing)
