Custom Conveyor Roller Bearing

Custom Conveyor Roller Bearing Manufacturer

As a Custom Conveyor Roller Bearing manufacturer, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.

Shanghai Yinin Bearing & Transmission Company is a China-based manufacturer and supplier of conveyor roller bearings, with over 20 years of experience in the bearing industry. We design and produce a range of conveyor roller bearings for material handling systems, including heavy-load conveyors, high-speed lines, and automated logistics equipment. Our factory in Jiangsu Province integrates manufacturing, quality control, and warehousing, allowing us to deliver both standard and custom solutions for OEM and aftermarket projects.

Our conveyor roller bearing line includes five series: MTR, W, MRC, KOLO, and BT. Each series is engineered for specific operating conditions, from light-duty belt conveyors to high-impact bulk handling systems. We also offer customized non-standard bearings for unique shaft dimensions, load requirements, and environmental conditions.

Our Conveyor Roller Bearing Range

Each series is available in chrome steel or stainless steel, depending on the operating environment. For food-grade or corrosive applications, we offer stainless steel options that resist washdown chemicals and moisture.

Engineering and Customization

We understand that standard bearings do not always fit the exact shaft, housing, or load profile of your conveyor system. Our engineering team works with you to define the correct bearing type, internal clearance, cage design, and sealing arrangement. We can adjust radial clearance during assembly to match your operating temperature and load conditions, using methods such as preload, shim adjustment, or locking nut adjustment.

For high-speed or high-precision lines, we provide preload adjustment to increase rigidity and reduce vibration. For applications with thermal expansion, we set the clearance to accommodate temperature changes and prevent seizure. Our technicians also support custom bore sizes, outer diameters, and width modifications for non-standard rollers.

Quality Assurance and Testing

Quality control is embedded in every production stage. We perform inspections after each process, from raw material incoming checks to final assembly. Finished bearings undergo full inspection according to customer requirements and international standards. Our factory is equipped with modern measuring tools and testing instruments to verify dimensional accuracy, radial clearance, and rotational smoothness.

We also conduct noise and vibration checks on conveyor roller bearings, as excessive noise often indicates improper clearance or surface defects. By controlling these parameters, we ensure stable operation and extended service life in your conveyor system.

Integration and Installation Support

Conveyor roller bearings must be installed correctly to achieve their rated performance. We provide mounting guidance for press-fit, shaft, and housing fits, as well as lubrication recommendations. Our bearings are supplied with appropriate grease for the expected temperature range and speed factor.

For automated conveyor systems, we can coordinate with your line integrator to ensure the bearing's load rating and speed capability match the drive and roller design. We also offer packaging options that protect bearings during transport and storage, including anti-rust coating and individual wrapping.

Information We Use to Configure Your Solution

To prepare a precise quotation and bearing configuration, we need the following project details:

• • Roller outer diameter, shaft diameter, and roller length
• • Operating load (radial and axial) and speed (RPM)
• • Ambient temperature, humidity, and exposure to dust or chemicals
• • Required service life and maintenance intervals
• • Mounting arrangement (press fit, set screw, or adapter)
• • Any non-standard dimensions or special materials (e.g., stainless steel)
• • Quantity per order and target delivery schedule

With this information, we can recommend the appropriate series and any necessary modifications. For complex projects, our technical team can provide drawings and test reports before mass production.

Maintenance and Serviceability

Conveyor roller bearings are designed for low maintenance, but periodic lubrication and inspection extend their life. We can supply bearings with lubrication holes or fittings for re-greasing in high-duty applications. Our spare parts support ensures that replacement bearings match the original specifications, minimizing downtime.

For large conveyor networks, we can help you standardize on a single bearing series to reduce spare parts inventory. Our sales team can also provide training for your maintenance staff on proper handling and installation.

Documentation and Training

Each shipment includes quality certificates, inspection reports, and packing lists. We can provide material certificates and dimensional reports upon request. For new installations, we offer installation and maintenance manuals that cover bearing fitting, lubrication, and troubleshooting.

Our team is available for online or on-site training sessions to ensure your engineers and technicians are confident with the bearing selection and maintenance procedures.

Frequently Asked Questions

What is the difference between MTR and W series conveyor roller bearings?

MTR series is designed for heavy-load and high-speed conveyor systems, offering higher load capacity and rigidity. W series is a general-purpose bearing for standard belt conveyors, providing reliable performance at moderate loads and speeds. If your conveyor operates under continuous heavy loads, MTR is the better choice.

Can you manufacture conveyor roller bearings with custom dimensions?

Yes, we specialize in customized non-standard bearings. We can modify bore size, outer diameter, width, and internal clearance to fit your roller design. Provide your shaft and housing dimensions, and we will engineer a bearing that meets your load and speed requirements.

What materials are available for conveyor roller bearings?

We offer chrome steel (GCr15) for standard applications and stainless steel (440C or equivalent) for corrosive or washdown environments. Stainless steel bearings provide excellent resistance to moisture and chemicals, making them suitable for food processing and outdoor conveyors.

How do you ensure the quality of conveyor roller bearings?

We conduct inspections after each manufacturing process and perform full inspection on finished products according to customer requirements and international standards. Our quality control system includes dimensional measurement, clearance verification, and noise testing to ensure consistent quality.

What is the minimum order quantity for custom conveyor roller bearings?

Our minimum order quantity is 100 sets for standard and custom bearings. This allows you to test prototypes or manage small-scale projects without large inventory commitments. For volume orders, we offer competitive pricing and flexible delivery schedules.

Do you provide technical support for bearing installation?

Yes, our technical team provides installation guidance, including recommended fits, tolerances, and lubrication. We can also supply detailed mounting instructions and offer training for your maintenance staff to ensure optimal bearing performance and longevity.
