Product Description
The LADA 21121006135 belt tensioner bearing, also known by part number 2112-1006135
and bearing reference 38-2243, is a precision-engineered timing belt tensioner pulley
designed to maintain optimal belt tension within the engine timing system. A properly
functioning tensioner bearing is essential for engine reliability — it prevents belt
slippage, reduces vibration, minimizes noise, and protects against catastrophic timing
failure that can lead to severe engine damage.
At Nexans Bearings (NKS Bearing), we supply this tensioner bearing to aftermarket
distributors, auto parts wholesalers, and OEM customers across global markets, backed
by over 30 years of bearing manufacturing and sourcing expertise.

Q1: What is the OEM part number for this belt tensioner bearing?
The primary OEM part number is 21121006135, also referenced as 2112-1006135,
with bearing reference 38-2243. Cross-check with GATES or CONTITECH catalogs
for additional interchange numbers.
Q2: What vehicles is the LADA 21121006135 tensioner bearing compatible with?
This tensioner pulley is designed primarily for LADA vehicles. Please confirm
exact fitment using your vehicle's OEM part number or consult our technical team
for application guidance.
Q3: How does a belt tensioner bearing work?
The tensioner bearing (tensioner pulley) applies consistent pressure to the timing
belt, keeping it taut throughout engine operation. This regulates belt tension,
minimizes belt slip and noise, and ensures accurate timing between the crankshaft
and camshaft — critical for engine efficiency and preventing valve damage. [1]
Q4: What are the signs of a failing belt tensioner bearing?
Common symptoms include: squealing or grinding noise from the engine bay, visible
belt wear or fraying, belt misalignment, engine misfires or rough idling, or a
visibly wobbling/seized tensioner pulley. Prompt replacement is strongly recommended
to avoid timing belt failure and potential engine damage. [0]

Q9: What is the difference between LADA 21081006120 and 21121006135?
Both are LADA timing belt tensioner bearings, but they differ in dimensional
specifications and application fitment. The 21081006120 (38-2242) and
21121006135 (38-2243) are designed for different LADA engine variants.
Always verify using your vehicle's specific OEM part number to ensure correct fitment.
