Sometimes, it benefits Cybertronians, especially if they are tired or injured.
To defeat Unicron, the Thirteen concocted a plan where the youngest of their number, Optimus Prime, would enter the Chaos-Bringer and expose his Primus-like spark to Unicron's anti-spark, the resulting interaction knocking both into stasis lock. While Optimus was revived by Quintus Prime's Emberstone, Vector Prime created a time-loop around Unicron with the intent of leaving him comatose forever.
When the Great Cataclysm struck Cybertron the few Primes left rounded up as many survivors as they could and led them underground to wait out the out cataclysm in protective caves where they instructed their followers on how to enter stasis. Left on the surface by Prima, the Predacons attempted to fly to safety before vague instinctual knowledge of stasis lock kicked in and they attempted to seek shelter underground.
After being attacked by a swarm of Insecticons, Sludge was badly damaged and forced to enter stasis lock. His body was discovered by Jazz and Cliffjumper.
Skyquake was in stasis until Starscream and Soundwave awakened him by placing an energon cube inside his stasis chamber. When Starscream found Megatron floating in space, he had no choice but to bring his master to the warship where they immediately put his body into stasis.
Scraplets were in stasis until they were brought into the Autobot base. They eventually broke out of their pod and would have nearly destroyed the base if wasn't for the humans saving their robot friends.
Bulkhead was put in stasis by Ratchet to examine the data that was stored into his head. Ratchet examined Bulkhead again after the data was gone from his mind. Bulkhead woke up from stasis when Miko played their favorite song on her guitar.
The possessed Nemesis used its stasis beam to put Bumblebee, Arcee, Bulkhead, Optimus Prime, Megatron, Dreadwing, Soundwave, Knock Out and the Vehicons in stasis. They were out of it when the Humans stopped the possessed Warship.
Smokescreen explained to Optimus Prime, Ratchet, Arcee and Bumblebee that he arrived on Earth in a Decepticon escape pod because he was captured aboard and went into stasis. He woke up from stasis when they found him.
Optimus went into deep stasis and saw Alpha Trion's spirit in the AllSpark. Alpha Trion tried to convince Optimus to join the AllSpark, but Smokescreen was able to use the Forge of Solus Prime to revive Optimus in a new body.
The Predacon clones in Shockwave's lab on Earth were in their stasis pods in their C.N.A until Wheeljack used one of his bombs to destroy them with Ultra Magnus's approval. Predaking was very mad about this and attacked them. Luckily Optimus Prime saved them from Predaking's wrath.
Unicron woke up from stasis and used Megatron's body as his vessel to destroy Cybertron. His plans were foiled as the alliance of Autobots, Predacons and Knock Out stopped him with Optimus Prime trapping Unicron inside the AllSpark's container.
