SW 016419-01MX New Condition: ISRI NTS1 Damper Shaft Kit for VOLVO Trucks
In the operation of VOLVO trucks, the ISRI NTS1 series seats are widely used for their excellent shock absorption performance. However, data shows that 78% of such seats used for more than 2 years experience wear failure of the original Damping shaft kit — rust on the damper shaft and bearing jamming cause a 50% increase in seat jitter transmission rate, and a 40% surge in drivers’ lumbar fatigue rate after long-haul trips. This not only affects driving comfort but also shortens the overall service life of the seats.
As a brand specializing in heavy-duty truck seat parts, SW has recently launched the new-condition (OE:016419-01MX) damper shaft kit, positioned as a Volvo truck parts product. It is precisely compatible with ISRI NTS1 seats and mainstream VOLVO heavy-duty trucks (such as FH and FM series). Through material upgrades and structural optimization, it provides an all-in-one solution to the wear pain points of the original damper shaft kit.
I. Core Advantages: Durability + Compatibility + Easy Installation, Redefining VOLVO Truck Shock Absorption Experience
This 016419-01MX kit is not an ordinary repair part but deeply optimized for high-frequency stress scenarios of Damping shaft kit, balancing performance and practicality:
1. 40Cr Alloy Steel Material, 2.5x Longer Service Life Than Original
As a core component of Volvo truck parts product, the kit breaks through the limitations of original parts in materials and processes:
- Fatigue Resistance Enhancement: Adopts 40Cr high-strength alloy structural steel, treated with overall quenching and tempering (hardness up to HRC28-32), with a tensile strength of 800MPa — 40% higher than the original ordinary carbon steel damper shaft (tensile strength 560MPa). It can withstand 100,000 cycles of high-frequency vibration impact without deformation;
- Anti-Rust Upgrade: The shaft surface is coated with hard chrome (thickness 0.05mm) + passivation treatment, showing no rust after 120-hour salt spray test. It adapts to harsh environments such as rain, snow, and humid mining areas, avoiding the "6-month rust jamming" problem of the original damper shaft;
- Bearing Optimization: The supporting bearing uses imported German double-row angular contact ball bearings, with a friction coefficient as low as 0.0015 — 60% lower than the original bearing’s rotational resistance. There is no jamming or abnormal noise when adjusting the seat, and the smoothness is significantly improved.
A driver from a VOLVO FH logistics fleet commented: "Previously, the original Damping shaft kit jammed after more than 1 year of use; after replacing with SW 016419-01MX, there was no increased jitter in 2 years, and all drivers said ‘the seat feels like new’."
2. 1:1 Precise Compatibility, Covering VOLVO + ISRI NTS1 Full Scenarios
- Dual Compatibility: It not only precisely matches the shock absorption mechanism of ISRI NTS1 seats (shaft length 185mm, mounting hole diameter Φ20mm, fully consistent with the original) but also serves as a Volvo truck parts product compatible with VOLVO FH (post-2018 models), FM, FH16, and other series heavy-duty trucks. In-place replacement is possible without hole expansion or modification;
- Accessory Integrity: The kit includes all components such as damper shaft, bearing, dust cover, and fixing nut. No additional purchase of scattered parts is needed, allowing maintenance personnel to perform "one-stop installation" and avoiding the trouble of "time-consuming separate purchase" of original parts;
- Compatibility Verification: According to third-party testing, the kit has no conflict with the pneumatic system and adjustment mechanism of VOLVO truck seats. After installation, it does not affect the original functions such as seat lifting and backrest angle adjustment, with a compatibility success rate of 100%.
3. 15-Minute Quick Installation, No Professional Tool Threshold
- Tool Simplification: Only basic tools such as a 17mm open-end wrench and circlip pliers are needed. Remove 4 fixing screws at the bottom of the seat, take off the old kit, and fasten it to the mounting position. No hydraulic equipment or special fixtures are required;
- Clear Installation Guide: The kit is accompanied by a graphic manual, marking the installation direction of the damper shaft and the assembly sequence of the bearing. Even maintenance personnel without experience can operate according to the diagram, avoiding shock absorption failure caused by reverse installation;
- Instant Effect: No shock absorption parameter debugging is needed after installation. The seat jitter transmission rate immediately drops from 60% to 25%, and drivers can intuitively feel the reduced vibration without waiting for a "running-in period".
III. Scenario Adaptation: Covering Core Operational Needs of VOLVO Trucks
1. Long-Haul Logistics: Shock Absorption Protects Waist & Improves Efficiency
2. Truck Maintenance Shops: Efficient Compatibility Reduces Inventory
3. Old Vehicle Renovation: Low-Cost Performance Restoration
