How to Choosing Teeth and Adapters

Tips and adapters (or tooth supports) are essential instruments for successful excavation and efficient material handling.
It is necessary to select the most suitable teeth and adapters for every specific situation according to their characteristics, type of application, and machine model.

Teeth and adapters are distinguished by type, profile, and fixing system when equipping buckets for loadrs, eexcavators, and mini-loaders. The required application also determines the selection of tooth type and profile. In this discussion we will set out the necessary information in order to equip your machine with the right products.

How to identify the most suitable teeth and adapters?
To identify the right adapter, it is first necessary to establish:

What machine the set of teeth and adapters will be installed on (e.g. loader, bulldozer, grader, excavator).

Whether the bucket on which the adapters will be fitted is original or after-market.

The thickness of the bucket blade in question.

If it is necessary to choose teeth as well as adapters, it is important to establish the following.

1. How the tooth is fitted to the relevant adapter

There are four main fixing systems:

1. Horizontal on the side

ASSEMBLY 1U3352 + 3G8354 + 1140358 + 1140359 1 ITR ASSEMBLY 23SP + D.834.23 + 23FP

2. Vertical on the side

ASSEMBLY V17TYL + 833.V17 + V13.17PN 1

3. Vertical in the centre

4. Bolted directly to the bucket blade


2. What elements are used in the fixing system

1. Single steel element fixed with retainer

PINS 1140358 + 1140359

2. Elastic steel pin (single element in rolled steel)


3. Single steel U-shaped element


4. Single steel element with rubber fixture

PINS 25 30PN + 25 30LK

5. Single element comprising steel and rubber parts


3. How is the tooth pocket shaped

Rectangular cross-section

Oval cross-section

Triangular cross-section

Spiral protrusion

Once the tooth model has been identified, the profile and size must be established

4. Tooth size

The size means the dimensions the tooth must have for correct coupling to the adapter. Size is identified mainly by the internal dimensions of the tooth pocket. The size also provides an approximate indication of the tonnage category of the machine on which the tooth-adapter-fixture kit will be installed. The larger the size, the greater the tearing force to which the tooth-adapter-fixture system can be subjected.

5. Tooth profile

It is essential to establish the tooth profile since there are specific profiles for each different application. Fitting the wrong profile could result in early tooth wear, breakage after a few hours of use, or the well-known “balling” wear effect rather than remaining sharp.

Application and machine model: everything there is to know about choosing the right teeth Choosing Teeth and Adapters
Teeth can be categorized by application, which means the type of terrain in which the wearing elements will be used, and the type of machine on which they will be installed. They can thus be divided up into:
Teeth for lighter or heavier application Choosing Teeth and Adapters
Excavator teeth
Loader teeth
