In any NISSAN truck or commercial vehicle running a two-piece driveshaft, the center support bearing is a small component carrying a large responsibility. Sitting between the transmission and the differential, the NISSAN driveshaft center support bearing (OEM 37510-90019) holds the propshaft in alignment, lets it flex under load, and isolates the cab from driveline vibration. When this center bearing wears, drivers feel it first as humming, shudder, or a clunk on acceleration — and ignoring it accelerates wear on the driveshaft, U-joints, and differential. A correctly specified center support bearing protects the entire driveline.
Technical Overview: Structure, Material & Performance
The center support bearing 37510-90019 — also called a carrier bearing, hanger bearing, or intermediate bearing — is an assembly of three functional elements working together:
1. Sealed Ball Bearing Core
At the center is a sealed, pre-lubricated radial ball bearing that supports the rotating propshaft. The seals retain grease and exclude water, dust, and road debris, so the bearing arrives ready to install with no field re-greasing required. Sealing integrity is critical for commercial duty cycles, where exposure to spray and grit is constant.
2. Rubber-to-Metal Bonded Cushion
Surrounding the bearing is a precision-molded rubber cushion bonded to the steel components with a dedicated bonding agent. This rubber — typically a natural/SBR blend mixed to a controlled durometer — performs two jobs at once: it dampens torsional and bending vibration from the driveshaft, and it allows the small amount of flex and misalignment that a two-piece shaft requires. Bond strength and rubber hardness are the two variables that most determine service life, which is why both are process-controlled in OE-grade parts.
3. Heavy-Gauge Steel Bracket & Fasteners
The outer housing and mounting bracket are formed from heavy-gauge steel for rigidity and fatigue resistance, then finished to resist corrosion. Mounting hardware uses heat-treated grade-5 bolts. The bracket bolts directly to the vehicle crossmember, transferring load into the chassis while the rubber cushion isolates vibration.

Performance Advantages
• Lower NVH: controlled-durometer rubber damps vibration to OE levels, keeping the cab quiet and comfortable.
• Driveline protection: correct alignment and flex reduce stress on U-joints, slip yokes, and the differential.
• Durability: heavy-gauge steel and a verified rubber-to-metal bond withstand heavy-duty load cycles and heat.
• Fast fitment: sealed, ready-to-install design cuts workshop labor and warranty risk.
FAQ
Q: What are the symptoms of a failing NISSAN center support bearing?
A: Common signs include a humming or growling noise that changes with speed, vibration through the floor at highway speeds, and a clunk or shudder on initial acceleration. A visual check often shows cracked, hardened, or separated rubber around the bearing.
Q: Is 37510-90019 a direct OEM replacement?
A: Yes. This part is engineered as an exact-fit replacement for NISSAN OEM 37510-90019, with bore, width, and bracket geometry matched to the original. We recommend confirming the OEM number stamped on your old part before ordering.
Q: What rubber and bearing quality do you use?
A: We use a natural/SBR rubber compound mixed to a controlled durometer and bonded with a dedicated rubber-to-metal bonding agent, paired with a sealed, pre-greased ball bearing. Bond strength and hardness are tested under our IATF 16949 system.
Q: Does the bearing come pre-greased and sealed?
A: Yes. The ball bearing is sealed and pre-lubricated with a dust shield, so it is ready to install with no field greasing. This protects against water and grit ingress during commercial service.
Q: Can you supply by OEM cross-reference or sample?
A: Absolutely. Send us the OEM number, a sample, or a technical drawing and we will match or develop the exact part. Cross-referencing by OEM 37510-90019 is the fastest route to a correct quote.
Q: What is your MOQ, lead time, and packaging?
A: MOQ, lead time, and packaging are flexible to your order volume. We support neutral packaging, custom branding, and export-standard cartons. Contact us with your target quantity for an exact quotation.
Q: Do you offer OEM/ODM and private-label supply?
A: Yes. As a manufacturer we support OEM and private-label programs, including custom markings, packaging, and documentation for importers, distributors, and OE buyers.
Q: Which certifications and export documents can you provide?
A: Our quality system covers IATF 16949, ISO 9001, and ISO 14001. We can provide material and inspection documentation and standard export paperwork to support customs and aftermarket distribution.
