SP128563 Bearing is a heavy‑duty rolling bearing applied for transmission or axle assembly of LiuGong wheel loaders. It bears large radial and axial loads during equipment operation, reduces rotational friction for shafts and related rotating assemblies, and guarantees stable rotation of power transmission parts.
Operating under harsh construction‑site conditions with heavy shock load, dust and moisture invasion, bearings will suffer raceway wear, rolling element damage and clearance increase after long‑time cyclic loading. A defective bearing will generate abnormal noise, high operating temperature, vibration and jitter. If kept in service, it may further damage shafts, housings and other mating core components, leading to unexpected machine shutdown and high repair cost.

FAQ
Q1: What symptoms indicate the bearing needs replacement?
Replace in time when abnormal running noise, excessive heating, obvious vibration or increased rotational clearance occurs, to avoid secondary damage to shafts and housings.
Q2: What is your delivery lead‑time?
In‑stock goods ship within 3‑7 working days. For out‑of‑stock items, we confirm exact lead‑time with you prior to order confirmation.
Q3: How do you ensure quality for heavy‑duty bearings?
We cooperate with verified domestic qualified suppliers, carry out appearance and dimension spot‑check before shipment to meet LiuGong assembly requirements.
Q4: What does warranty cover?
6‑month warranty covers manufacturing defects. Damage caused by improper installation, insufficient lubrication, heavy impact and normal fatigue wear is excluded from warranty scope.
Q5: How can I receive quotation for SP128563 bearing?
Submit part number, purchase quantity and delivery destination, our sales team provides detailed quotation within 24 hours.
Installation Guide
Clean bearing housing and mating shaft thoroughly before installation, remove metal debris, burr, dust and old grease residue.
Inspect new bearing for rust, crack, dent and surface damage, reject any defective unit. Do not remove anti‑rust protection until installation.
Adopt correct installation method; avoid direct hammer striking on bearing raceway to prevent premature damage.
Ensure proper fitting clearance, fill with specified amount of lubricant after mounting.
After installation, rotate the assembly manually to confirm smooth operation without jamming or sticking.
Maintenance Tips
Check bearing temperature, noise and vibration status during each 500‑hour service interval.
Maintain correct lubrication grade and filling quantity; insufficient or contaminated grease is the main cause of early bearing failure.
Replace bearing promptly once abnormal noise or overheating appears, do not continue operating with defective units.
During overhaul, inspect mating shaft and housing for wear or deformation, repair related positions if necessary.
