Anhui Lianjun Rubber Technology Co., LTD. is a China-based manufacturer of NVH rubber damper elements for Mercedes-Benz and BMW chassis systems. Our driveshaft support bearing line is the Driveshaft Center Support Bearing range: center support bearings, carrier bearings and propshaft intermediate bearing assemblies that stabilize multi-piece drive shafts in rear-wheel-drive and all-wheel-drive drivelines.
Production is based at our 13,000 square meter Ningguo, Anhui facility, where we also manufacture engine mounts, transmission mounts, strut mounts, bushings and flex discs under a broader NVH product program. Free sample support is available for qualified projects, allowing engineering and procurement teams to evaluate fit, rubber damping and bracket geometry before batch commitment.
Driveshaft Support Bearing Range
We structure the driveshaft support bearing line around the two Mercedes-Benz and BMW platform families most common in aftermarket distribution and service operations.
For W124, W201, W202, W210, W639, Sprinter 906 and T1/T2 series, the line includes OE-matched center support bearings and carrier bearing assemblies. Typical applications cover passenger cars, vans and light commercial drivelines.
For E34, E39, E46, E53, E60/E61, E84, E90 and F-chassis xDrive series, the range includes rubber-damped center support bearings and bridge bearing assemblies for RWD and AWD propshafts.
- Both lines are organized by OE number and chassis code for quick matching.
- Assemblies are available as complete support bearing units, not loose bearing inserts, where the vehicle requires bracket and rubber isolator replacement.
- Related driveline service parts such as the Driveshaft Flex Disc Kit can be supplied alongside support bearings for combined driveline service orders.
Application Fit and NVH Behavior
A center support bearing is selected for how the propshaft is segmented, the working angle, and the NVH transfer path from the driveline into the body. In Mercedes-Benz and BMW vehicles, the support bearing works with the flex disc, center bracket and transmission mount to keep the shaft aligned and isolate bearing-induced vibration.
- RWD and AWD vehicles where a two-piece or multi-piece propshaft requires a centered intermediate support.
- Diesel and high-torque variants where driveline load changes make rubber isolation more demanding.
- Fleet and specialist vehicle programs requiring repeatable OE-fit replacement parts.
- Service situations where worn rubber or a rough bearing causes take-off shudder, speed-related vibration or metallic noise.
Material, Sealing and Selection Variables
We configure each support bearing around the bracket geometry, bearing fit and rubber damping requirement. The bearing element is enclosed where the vehicle design requires contamination protection, while the rubber isolator is compounded for damping, temperature resistance and service life.

Engineering, Mold Development and Customization
The R&D team supports catalog matching and new development for additional Mercedes-Benz and BMW chassis applications. This includes mold development, sample validation and production documentation, supported by the broader 13,000 square meter manufacturing footprint.
- Free sample support for visual and dimensional evaluation before production order.
- OE number cross-reference and product code alignment for distributor and fleet purchasing.
- Custom mold development for non-catalog vehicle applications where volume supports tooling.
- Batch-level traceability from incoming rubber and bearing components through finished support bearing assembly.
Quality Control and Acceptance
Quality control for driveshaft support bearings covers incoming elastomer and metal components, cure and bonding process control, dimensional checks, bearing function checks and final packaging. The quality management system follows ISO9001 and IATF 16949 process disciplines for production traceability and continuous improvement.
- Incoming compound and bearing component inspection before production release.
- In-process control of vulcanization, bonding and bracket assembly.
- Finished-part dimensional, durometer and visual inspection against the approved sample.
- Pre-shipment verification for each order, with sample approval available before batch completion.
Installation, Service and Spare Parts
Our center support bearing assemblies are supplied as complete replacement units where the production vehicle uses an integrated bracket and rubber isolator. Installation is normally carried out with the propshaft removed, the support bracket aligned to the vehicle mount points, and fasteners secured to the vehicle manufacturer specification.
- Visual inspection should cover rubber cracking, bond separation, cage roughness and excessive radial play.
- Replacement is typically considered when driveline vibration, acceleration shudder or speed-related noise is present.
- Packaging protects the rubber isolator and bracket during transit and warehousing.
Information We Use to Configure Your Solution
To prepare a configuration and quotation, our team works from the following project data. This keeps the proposal aligned with part number, application and delivery requirements.
- Vehicle model, year, chassis code and OE number for each item.
- Required bearing assembly type: bracket-mounted, hanger-type, bridge-type or complete propshaft support unit.
- Initial sample quantity and annual estimated volume.
- Target market, packaging requirement and any private-label or customer part numbering.
- Existing sample, drawing or damaged original part if the application is not already in our catalog.
Frequently Asked Questions
Can you provide free samples for evaluation?
Yes. We support free sampling for qualified projects so customers can check fit, rubber damping and finished assembly condition before placing a production order.
Which vehicle platforms does the driveshaft support bearing range cover?
The range covers common Mercedes-Benz and BMW rear-wheel-drive and all-wheel-drive chassis. Catalog items are organized by OE number and include passenger car, SUV, van and light commercial applications.
Can you produce support bearings for applications not shown in the catalog?
We provide mold development and custom matching for additional Mercedes-Benz and BMW applications where expected volume supports tooling and development work.
What information do you need for a quotation?
Vehicle model, chassis code, OE number, required assembly type and estimated quantity are the core inputs. A sample or original part helps when the item is not a catalog match.
Do you supply related driveline parts with support bearings?
Yes. We manufacture related NVH chassis parts, including flex discs, transmission mounts and engine mounts, so a driveline service order can be consolidated.
