Packaging machinery runs at high speed and frequency, and the original bearings had an average service life of only 6 months. Frequent shutdowns for replacement caused serious losses in capacity.

We adopted MAOZE LMF-TR high-precision flanged linear bearings and optimized the lubrication scheme and mounting method to extend service life.

Average bearing service life was extended to 18 months, equipment downtime was reduced by 70%, and overall maintenance costs decreased by 45%.

The customer's original domestic spindle lacked the precision required for high-accuracy cylindrical grinding. After replacing it with an SLF precision grinding spindle, machining accuracy improved significantly.

Customer Challenge

The original spindle achieved only 3μm accuracy, falling short of the customer's requirement of within 1μm, and its short service life caused frequent maintenance that disrupted production efficiency.

MAOZE Solution

We selected an SLF belt-driven precision grinding spindle paired with SLF application-optimized bearings, providing full-process technical support from selection through installation and commissioning.

Key Results

Machining accuracy improved to within 0.8μm, spindle service life was extended by more than 3 times, annual maintenance costs were reduced by 60%, and customer capacity increased by 25%.

High-speed motors running at 15,000 rpm caused excessive temperature rise and short service life with ordinary bearings, while imported brand bearings were expensive and had long lead times.

We recommended SLF hybrid ceramic ball bearings with self-produced ceramic rolling elements and a special lubrication scheme, effectively reducing temperature rise while maintaining precision.

Bearing temperature rise decreased by 35%, service life doubled, procurement cost dropped 30% compared with the original imported brand, and lead time was cut to one third.

The automated production line used linear bearings in large quantities, with annual purchases exceeding 5,000 units. Japanese brands were expensive with lead times up to 8 weeks, seriously affecting line delivery.

We recommended MAOZE ST series super linear bearings, provided free sample testing, and offered on-site support from our technical team for selection and replacement to ensure a seamless switch.

Procurement cost decreased by 55%, lead time was shortened to 2 weeks, product performance matched the Japanese brand, and annual purchasing costs were reduced by more than RMB 800,000.
