Description

Overview

SAF Intra 350 Air Spring Assembly supports consistent trailer ride height and load control in SAF Intra air suspension setups. Replacing a leaking or fatigued bellows helps protect tyres, reduces harshness, and keeps the suspension working as intended. It also suits applications that run up to 7 bar operating pressure and see wide temperature swings in Australian conditions.

Features

This SAF Intra 350 Air Spring Assembly is supplied as a complete service assembly for suspension maintenance. It is designed to handle typical trailer articulation and vibration while maintaining air retention.

• Max operating pressure of 7 bar (100psi) for common trailer air systems
• Operating temperature range from -40°C to +70°C for year round use
• Designed to suit SAF Intra suspension layouts that use a 350mm air spring size
• Helps maintain stable ride height and improves load support when correctly installed

Specifications and Materials

This assembly uses a reinforced rubber air bellow with metal end components for clamped, sealed installation. Correct mounting surface condition and fastener torque are critical to long service life. Part number: SP0121A.

Compatibility and Fitment

This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. SAF HOLLAND 229.0028.00, SAFHOLLAND229002800, 229002800, P10.2923.CP, P102923CP

Compliance and Safety

Depressurise the air system before removal, then support the chassis safely to prevent sudden movement. Inspect the air lines and height control components for damage because upstream faults can quickly ruin a new spring. After installation, confirm there are no leaks by performing a soap test and monitoring ride height.

Trailer Applications

This SAF Intra 350 Air Spring Assembly typically suits trailer suspension service where a complete air spring is required rather than a bellows only repair. It is also a practical choice for fleets that prioritise predictable handling and reduced component wear.

• General freight and curtain sider trailers using SAF Intra air suspension
• Tipper and tanker trailers where ride stability matters under varying loads
• Linehaul combinations that operate across hot and cold regions
• Trailer rebuilds where air springs are replaced as a matched set
