In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
Learners in the field of engineering require the skills, values and knowledge reflected in this unit standard.

The learning outcomes in this unit standard also contribute to the exit level outcomes required for the National Certificate in Engineering Fitting (NQF level 3) and related qualifications.

Qualifying learners are able to identify a range of bearings and their application in machinery and equipment and are able to check bearings, determine faults, assess requirements for repair, and remove and replace bearings. 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
This unit standard has been designed as part of a progression. It is one of a series of unit standards for machine installation in the engineering area.

The credits allocated to this unit standard assume that a learner has already learned to perform routine maintenance. 

UNIT STANDARD RANGE 
The ranges as indicated under the specific outcomes determine the scope and level of this unit standard.

The learner should be able to work autonomously with minimal supervision and according to worksite and manufacturer specifications and occupational safety, health and environmental legislation.

Work is generally, but not exclusively, carried out in a team environment.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
