ISK custom bearing services cover three areas: the bearing itself (dimensions, tolerance, material, seal), brand identity (laser marking, custom packaging), and a complete process from first discussion to volume production. The goal is straightforward — to find a bearing that genuinely fits your application, rather than forcing an off-the-shelf specification to work.
Whether you are reordering an existing specification, need a special size that isn't available on the market, or are dealing with equipment running abnormally and need a fresh assessment, a good place to start is simply talking through your actual situation — we'll help you think the direction through together.
ISK offers a range of bearing materials, selectable by load, speed, temperature, corrosion environment, and insulation requirements. The table below lists the main materials ISK can customize and their typical application directions:
| Material | Characteristics |
|---|---|
| Si₃N₄ Ceramic | High hardness, high-temperature tolerance, lightweight, electrically insulating |
| Hybrid Ceramic | Ceramic balls with steel rings |
| ZrO₂ Ceramic | Corrosion resistant, chemical resistant, electrically insulating |
| Carbon Steel | General-purpose high load, mature process |
| Stainless Steel | Corrosion resistant, suited to clean environments |
| Engineering Plastic | Self-Lubricating, Lightweight, Heat-Resistant |
| Other Special Materials | Assessed per specific operating conditions or requirements |
Each material suits different operating conditions. Sharing your actual application and working conditions allows ISK to help assess a suitable material direction.
ISK can provide different seal formats based on dust protection, water resistance, lubricant retention, and running resistance needs. The table below shows three common seal formats and their suitable directions:
| Seal Type | Description | Suitable For |
|---|---|---|
| OPEN | No shield or seal | Applications with external lubrication or minimal running resistance |
| RS (Rubber Seal) | Rubber sealing | Environments needing dust protection, water resistance, or lubricant retention |
| ZZ (Metal Shield) | Metal dust shield | Applications needing dust protection while maintaining running performance |
The seal choice affects both protection and running characteristics, and can be discussed together with your environmental conditions.
ISK can laser mark your company logo directly onto the bearing, giving your product a dedicated brand identity. Beyond the bearing itself, ISK can also print your logo on the product box, creating a consistent brand presentation from component to packaging that helps your product stand out in the market.
The ISK customization process has four stages, tracked from clarifying the requirement through to volume delivery. A problem that standard products can't solve doesn't mean it has no solution — it simply calls for a different way of thinking. Across 30 years serving multiple manufacturing industries, ISK has built not only supply experience but cross-industry application judgment. Often, a similar need has already appeared in another industry, along with a way to handle it.
① First Discussion
Tell us about your equipment, operating conditions, or the situation you're facing, so we understand the real requirement.
② Diagnosis and Solution Confirmation
Based on the discussion, ISK assesses the root of the issue and feasible directions, then proposes concrete recommendations. Once the direction is confirmed, the implementation plan and preparations are aligned.
③ Sample Validation
Before formal production, a sample is produced for you to install and test. Volume production begins only after the sample meets your requirement — so issues aren't left to be discovered at full quantity.
④ Volume Production and Delivery
Production progress is tracked throughout to keep delivery predictable.
Every case goes through feasibility assessment and sample validation before entering production — a safeguard for you, and a standard ISK holds itself to.
If you already have a bearing model, dimensions, drawing, or sample, or are evaluating special materials, seals, brand laser marking, or packaging, share your application scenario and requirement details. ISK will help assess a suitable customization direction and the production arrangement that follows.
