Engineering & Custom Bearing Solutions
From replacement design to repeatable production
Complete engineering support for special bearing requirements—from equivalent replacement and non-standard design to material optimisation, prototype development, volume manufacturing and remanufacturing.
Not every bearing requirement can be solved through a standard catalogue. Equipment upgrades, imported-bearing replacement, discontinued models, special operating conditions, non-standard dimensions and ageing-equipment maintenance all require a fresh engineering assessment.
LZK combines bearing design, materials and heat treatment, precision manufacturing, inspection and application engineering to provide integrated technical support. Our engineering team develops the solution around the information and real conditions supplied by the customer.
01 / Equivalent Replacement
Imported and discontinued bearing replacement
When the original bearing is expensive, delayed, discontinued or difficult to source, LZK can perform a replacement analysis using the original model, technical drawings, a physical sample and the actual operating conditions.
For critical equipment, we focus on functional equivalence rather than simply copying the bore, outside diameter and width. Technical analysis, manufacturing and inspection are combined to create dependable replacement solutions for robotics, machine tools, precision rotary tables, gear reducers, energy equipment and large industrial systems.
02 / Non-standard Bearing Design
Designed around your application
When a standard bearing cannot meet the equipment requirement, we can redesign the bearing from the actual application conditions. Customers may provide an existing drawing or only the basic requirements: installation envelope, load, speed, accuracy, temperature, lubrication method and expected service life.
Our engineering team evaluates bearing type, rolling elements, raceway geometry, ring structure, materials, clearance, preload, cage, sealing and lubrication as one connected system.
Our objective is not merely to manufacture a bearing with different dimensions, but to ensure that the bearing truly matches the equipment's operating conditions.
03 / Bearing Repair & Remanufacturing
Restore performance and extend service life
Wear does not always mean that a large, high-value or long-lead-time industrial bearing must be replaced. Bearings with recovery value can be inspected and technically assessed before a repair or remanufacturing route is defined.
Depending on the inspection result, work may include raceway restoration, surface treatment, rolling-element replacement, cage replacement, accuracy recovery, reassembly and final verification.
For large rotary-table bearings, crossed roller bearings, slewing bearings and other high-value products, remanufacturing can reduce replacement cost and equipment downtime while still meeting the required technical standard.
04 / Material & Heat-treatment Optimisation
Balance hardness, toughness, wear resistance and stability
Many bearing failures are related not only to size or structure, but also to material, hardness, heat treatment and surface condition. High temperature, impact, corrosion, heavy load, high speed, frequent start-stop cycles and poor lubrication all require a fresh review of the material system.
According to the application, LZK can optimise hardness, hardened-layer depth, heat-treatment route and surface performance. The objective is not simply to pursue a higher hardness value, but to find the right engineering balance for reliable operation.
05 / Prototype Development
From drawing to working prototype
For new equipment, new structures and special bearing projects, prototype validation is essential before volume production. LZK supports the complete development route from technical concept to the first physical sample.
The prototype stage verifies the essential relationship between the drawing and the real machine.
We work alongside customer engineering teams on robotics, precision reducers, machine tools, semiconductor equipment, medical equipment and new automation systems—from initial concept through installation validation.
06 / Small-batch & Mass Production
From one prototype to repeatable production
Special-bearing programmes do not always begin with thousands of units. New equipment, maintenance projects, high-value machinery and specialist industrial applications often begin with a single sample or a controlled pilot batch.
After prototype validation, LZK can progress into small-batch manufacture and then into scaled production once the process, technical parameters and quality standards are confirmed. This model is particularly suitable for new-product development, imported-bearing replacement, non-standard machinery, robotics, machine tools and other advanced-equipment programmes.

Medical Equipment
Breaking dependence on imported bearings
Raceway soft-zone hardening and optimised spacers delivered the accuracy, torque stability and load capacity required by advanced medical equipment.
Semiconductor
Localising a critical rotary-table bearing
A purpose-developed nylon cage and controlled production route replaced a costly imported bearing while securing reliable local supply.
Machine Tools
Keeping an ageing gear-milling machine in service
Inspection, repair and a reverse-engineered replacement route reduced spare-parts cost and returned critical production equipment to operation sooner.
