Description
Overview:
This Grease Seal (30x40x4) is a non-genuine replacement designed for JCB 18Z-1 mini excavators, including the 18Z1 variant. It is a compact radial seal that helps keep lubricants in and dirt, dust, and moisture out, protecting bearings and rotating components from premature wear. Built from hard‐wearing, oil‐resistant elastomer with a reinforced construction, it offers dependable performance in tough site conditions. The 30 mm inner diameter, 40 mm outer diameter, and 4 mm thickness match common housings on compact assemblies found around mini excavator drivetrains and ancillary units. This cost‐effective alternative to OEM seals supports routine maintenance and repairs, helping restore smooth operation with minimal downtime on construction, landscaping, and plant hire equipment.
Key Features:
- Non Genuine Part for budget‐friendly maintenance without compromising core function
- Precise size: 30 mm ID × 40 mm OD × 4 mm width for a snug, reliable fit
- Oil‐resistant elastomer construction for use with standard mineral oils and greases
- Helps prevent lubricant loss and blocks ingress of dirt, grit, and water spray
- Supports longer bearing and bushing life by maintaining proper lubrication
- Slim 4 mm profile suits tight housings on compact machinery assemblies
- Stable sealing at typical excavator operating speeds and temperatures
- Easy to install with a standard press‐fit; reduces downtime during servicing
- Suitable for harsh site environments, including mud and wet conditions
- Practical choice for scheduled servicing or reactive repairs on small plant
Typical Applications:
Used to seal rotating shafts and housings on mini excavator subassemblies where a 30×40×4 mm seal is specified, such as small gearboxes, motor ends, idler or carrier bearing areas, and auxiliary drive components. Ideal for workshop rebuilds, on‐site repairs, and preventative maintenance to maintain lubrication and exclude contaminants.
Also known as:
Rotary shaft seal, lip seal, radial oil seal, grease ring, dust exclusion seal (secondary), rotary grease seal. These terms are often used interchangeably for axial or radial sealing elements that retain lubricants and protect bearings in compact machinery assemblies.
